Why is an AI Gateway no longer optional?
Tuesday May 26, 2026 10:00 - 10:30 CEST
While scrolling on Reddit, I found this interesting (yet frightening) post: “$82,000 in 48H from a stolen Gemini API key. My monthly usage is $180. Facing bankruptcy.” This story is a powerful reminder of why an AI gateway is a critical component in ADEO's AI governance.

In this talk, we will dive into the 'why' and 'how' of building an AI Gateway. We will share the inside story of how ADEO tackled this challenge through a strategic collaboration between the AI Services and DevPortal teams to create a secure, multi-provider entry point for our developers.

Pick’it: The path to standardizing the warehouse experience.
Tuesday May 26, 2026 10:00 - 10:30 CEST
We offer a retrospective on two years of hard work to revolutionize order picking in Decathlon warehouses with the Pick’it app. Originally designed to replace "Paper picking" in bulky item sectors, our mission was to turn it into the universal standard for order preparation.
This talk is not just a product presentation; it’s the story of a total field immersion and a fight for the survival of a product vision.

E-commerce Hackathon: Join the dark side to build better shields!
Tuesday May 26, 2026 10:00 - 11:30 CEST
As developers, we are constantly asked to "Shift Left," follow "Secure by Design" principles, and fix endless lists of vulnerabilities. But here is the reality: we are rarely taught how these flaws actually work or how an attacker exploits them. How can you effectively fix a vulnerability you can't even reproduce? How can you tell a critical threat from a false positive?

It’s time to bridge that gap.

In this session, Decathlon’s Offensive Security team pulls back the curtain. After a deep dive into Red Team methodologies and real-world attack vectors, it’s your turn to strike. Using professional tools like Burp Suite, you will be deployed onto a private e-commerce instance. Your mission? Stop being the target and become the attacker.

The Goal: By learning how to "pwn" the shop, you will finally understand the "why" behind security patches. Join the competition, climb the leaderboard, and win prizes while becoming the ultimate guardian of our ecosystem.

How to standardize internal front-end applications?
Tuesday May 26, 2026 10:45 - 11:15 CEST
At Decathlon, we have customer-facing applications, including one you all know: our e-commerce website.
This is based on our open-source design system : Vitamin Play.

But we also have many internal front-end applications.
The needs of these applications are very different from those of an e-commerce site.
Take navigation, for example. They are two completely different requirements.

Furthermore, these applications were built organically, and no guidelines exist to standardize them.
Imagine the tab titles in your browser: do you think simply displaying the application name is sufficient for a user to understand the page that is behind it?
And even worse, what if each application used by the same user is different in terms of design, user experience, etc.?

That's why we launched an initiative to produce guidelines and components that will standardize our internal applications for a better experience for our internal teammates, all without an allocated budget!

In this talk, we'll explain how we built this community, what our objective is, and what our initial achievements are.

From "baton passes" to building blocks: Making data work as a team sport.
Tuesday May 26, 2026 11:15 - 12:00 CEST
What do sports, home improvement, and modern AI have in common? None of them work well when handoffs are messy, foundations are shaky, or every new initiative starts by tearing down what already exists. This keynote explores how data products and data contracts help organizations create clearer ownership, stronger collaboration, and data that is truly ready for products, analytics, and AI through a practical, frugal, and brownfield-friendly approach.



In many organizations, the challenge is no longer collecting quality data. It is making that data trustworthy enough, with sufficient context, to be reused across teams, embedded in products, and pushed all the way into AI systems that actually reach production.

In this keynote, Jean-Georges “jgp” Perrin explores how data products and data contracts help organizations build stronger foundations for collaboration, delivery, and AI success. Using simple analogies from sport and construction, he shows why better outcomes depend on clean handoffs, explicit expectations, and assets designed to be reused rather than rediscovered every quarter.

The session also introduces Bitol, the Linux Foundation project advancing open standards for modern data engineering, including the Open Data Contract Standard (ODCS) and the Open Data Product Standard (ODPS). These standards are not abstract theory: they reflect a growing, proven practice in which data contracts and data products help teams reduce ambiguity, improve quality, and move AI initiatives from promising prototypes to production with greater confidence.

Most importantly, this is not a rip-and-replace story. It is a frugal, brownfield approach for real organizations: improve what exists, strengthen trust step by step, and create measurable value without wasting time, effort, or money. Built the way strong teams in sport, on worksites, and in the Nord often succeed best: with coordination, clarity, and something sturdy enough to last.

Agentic commerce 2026: When AI becomes your most important customer
Tuesday May 26, 2026 12:15 - 12:45 CEST
The e-commerce landscape is entering a long-term transition. While humans still hold the credit card, AI agents are increasingly taking over the discovery, comparison, and decision-making phases. With projections suggesting a significant portion of commerce will be agent-mediated by 2030, the shift for retailers starts now.

In this dual-voice session, a **Manager from the world of the Data** and a **Staff Software Engineer** bridge their perspectives to provide a pragmatic state of the union on Agentic Commerce. We will move beyond the hype to look at the incremental reality of this hybrid era:
* **Strategic Perspective**: How to remain relevant when an agent is filtering your catalog? We’ll discuss the shift in brand loyalty and the challenge of serving both human shoppers and their digital assistants.
* **Technical Foundations**: Preparing your stack for machine-to-machine interactions. We will cover the evolution of MACH architectures, the importance of goal-oriented APIs, and the role of standardized protocols like *MCP*.
* **Practical Scenarios**: From automated replenishment of consumables to "Intent-based" shopping, where agents orchestrate complex purchases across multiple categories.
Join us to explore the architectural patterns and strategic shifts that will bridge the gap between today’s web and tomorrow’s agentic ecosystem.

A11Y Ops: Solving 80% of accessibility barriers with 20% effort
Tuesday May 26, 2026 14:00 - 14:30 CEST
Think digital accessibility is an impenetrable maze of complex rules? Think again. We live in a golden age of tooling where ensuring your site is inclusive has never been more achievable.

- Kickstarting Accessibility: A quick introduction to accessibility, covering the creation of an accessibility statement and initial remediation efforts. Discover how to rapidly integrate accessibility tools into your product using AI and ready-to-use solutions.
- The Power of Automation: Discover how to leverage static and dynamic "safety nets" directly in your workflow to catch (a good) majority of errors before they even reach production.
- The Human Reality Check: Tools are powerful, but they aren't perfect. We will conclude with a practical, streamlined "First-Check" methodology designed to bridge the gap between automated scans and a full-scale expert audit. And prepare your product for legal compliance!

Key Takeaways: Don't aim for 100% perfection on day one. Instead, walk away with a toolkit to build a "healthy HTML base," automate your testing, and prepare your product for a future full audit with confidence.

Accessibility isn't a mountain—it's a series of smart, automated steps. Let’s take the first ones together.

Who said no budget means no global impact? P.O.P: A kaizen framework for self-funding a digital product
Tuesday May 26, 2026 14:45 - 15:15 CEST
Digital transformation often dies in the boardroom, waiting for a budget that never comes. But what if the lack of funding was actually your greatest competitive advantage?
In this session, we deconstruct the journey of a supply chain transformation that scaled from a zero-budget POV to a global platform supporting 1,500+ cross-functional users.
Faced with a heavy legacy process where a each day of excess stock cost millions in cashflow and shortages risked 3.5% of sales growth, our team bypassed the friction of traditional budget allocation by adopting a Kaizen-led, value-first approach
By repurposing legacy data and leveraging a "Digital squad" (UX, Product, Engineering, Data), we proved that factual impact silences political debate.
We will share:
- the exact blueprint used to define a high-impact "Initial Perimeter,"
- launch a low-cost MVP,
- and ultimately achieve worldwide deployment by making the value undeniable (very high ROI).

Key Takeaways:
- The "Shadow" Discovery: How to use legacy data to quantify the "Cost of Inaction" (e.g., the millions of cashflow lever).
- Governance Hack: Using factual data to navigate complex "Comittology" and resource scarcity.
- The Kaizen Scale: Moving from a complex muda workflow to a simple, efficient workflow with a company-wide standard without a "Big Bang" budget.

The Art of Effective BDD: Unleash the Potential of your Java Microservices
Tuesday May 26, 2026 15:00 - 16:30 CEST
Summary: Do you find testing your Java microservices tedious? Discover how we at Decathlon use Cucumber and the open-source library Tzatziki to test our applications effortlessly. By combining the expressive power of Cucumber—which allows for writing tests in natural Gherkin language—and Tzatziki’s ready-to-use modules, we have created an approach at Decathlon that drastically simplifies our integration and end-to-end testing. In this hands-on workshop, you will learn how to leverage Cucumber and Tzatziki to test every aspect of your Java microservices, finally reconciling functional understanding, development speed, and test quality.

Content: During this workshop, we will start by introducing Cucumber and the BDD approach we have adopted at Decathlon. You will discover how Tzatziki, our Cucumber Java extension, drastically simplifies the writing of integration tests and allows you to express business requirements in natural language.

We will follow up with three practical exercises.

The first will allow you to test a complete CRUD application with a PostgreSQL database, manipulating and verifying database data without needing to write code.

In the second exercise, you will learn how to mock external API responses while verifying your application's outgoing calls, thus mastering the HTTP interactions of your microservices.

The third exercise will introduce you to Kafka stream testing, where you will discover how to read, write, and validate messages using Avro schemas or JSON format.

Finally, we will tackle a fourth exercise dedicated to testing MCP servers using the new tzatziki-test-mcp module. Because yes, validating your MCP server is crucial before going to production, you will learn how to ensure it is reliable and ready for deployment.

Audience: This workshop is designed for Java developers from beginners to experienced professionals who wish to refine their knowledge of testing and master new tools to improve their workflow.

Zero UI: Why tone of voice & personality are the new UX
Tuesday May 26, 2026 15:30 - 16:00 CEST
Hook : For decades, we’ve been obsessed over pixels, grids, and "where to put the button." But in a world where screens are fading and Generative AI is becoming our primary interface, what happens to UX when there is no UI? As we move toward a Zero UI future, the "look and feel" of a brand is being replaced by the "sound and soul" of its conversation.

Pitch :
The era of the graphical user interface (GUI) is reaching its peak, making way for a paradigm shift: The Conversational Era. As AI agents become ubiquitous, the traditional tools of a designer—typography, color palettes, and layout—are becoming secondary. In this new landscape, the interface is invisible, and the interaction is purely linguistic.

In this talk, we will explore why Tone of Voice & Personality have become the new fundamental pillars of design. We’ll discuss:

- The Transition to Zero UI: Why the most sophisticated interface is the one you can’t see.

- Personality as Navigation: How an AI’s persona guides user behavior more effectively than a menu.

- Designing the Invisible: New frameworks for designers to transition from visual architects to conversational strategists.

- Cybersecurity Impacts : New approaches to jailbreak AI Conversational Agents

Whether you are a designer, a product manager, or a developer, it’s time to stop thinking in screens and start thinking in term of conversation & personality. The future of UX isn't something you see—it's something you feel through a conversation.

IA11Y: What's next for accessibility with AI?
Tuesday May 26, 2026 16:30 - 17:00 CEST
2025 was supposed to be a major year for accessibility with the enforcement of the European Accessibility Act. But the AI tsunami came in and stole the show! The future of technology seems inextricable of artificial intelligence. However is AI and Accessibility really a good mix ?

People with disabilities are already using AI tools in their daily lives: to navigate the web, understand content, or overcome barriers that were previously difficult to address. At the same time, AI-generated interfaces and AI-assisted development introduce new challenges: inaccessible tools, biased outputs, unreliable alternative text, or code that looks correct but fails basic accessibility requirements.

This talk looks at the current intersection between accessibility and AI. Through practical examples and a case study of a “vibe-coded” website, we will explore where AI can genuinely help improve accessibility and where it still falls short. The goal is not to present AI as a solution to accessibility, but to understand how it can support the work of designers and developers without replacing the human perspective that accessibility ultimately depends on.

From autocomplete to AI teammate: Supercharging QA automation with GitHub Copilot & MCPs
Tuesday May 26, 2026 17:00 - 17:30 CEST
**From Autocomplete to AI Teammate: Stop Wasting Time with GitHub Copilot**

We have all been there: fighting with AI hallucinations, stuck in endless prompting loops, and spending more time debugging AI-generated code than it would have taken to write it from scratch. AI can actually be a massive time-waster if used poorly.

As a QA Automation Engineer, I decided to stop treating GitHub Copilot as a simple code generator and turned it into a context-aware teammate. In this talk, I will share how to bridge the gap between business requirements and test automation without ever leaving Visual Studio Code.

Through personal stories of my own failures and successes, we will explore how leveraging Model Context Protocol (MCP) integrations for Playwright, Jira/Confluence, and Sonar creates a seamless, time-saving workflow. We will see how providing the *right* business context directly inside the IDE prevents AI hallucinations and generates clean, reliable Java/Playwright tests.

**Key takeaways:**
* **The AI Time Trap:** Why AI makes us lose time and how to fix it with proper context.
* **The "Teammate" Mindset:** Shifting from dumb code generation to smart, context-aware problem solving.
* **Accessible to All:** Practical, easy-to-implement techniques suitable even for junior developers—no AI expertise required.

Paramethor: Leveraging feature flipping for Decathlon
Tuesday May 26, 2026 17:45 - 18:15 CEST
How can hundreds of in-store applications adapt instantly to the specificities of a country, a sport, or even a single user, without any code deployment? This is the challenge we took on with**Paramethor**.

In this presentation, we will look back at the genesis of this product, born from a critical need at Decathlon: **reducing Time-to-Market** (TTM) and avoiding the sprawl of configuration databases. We will explore how we built a robust solution consisting of a high-performance backend, an intuitive admin interface, and a real-time notification system via Kafka to inform applications of every change.

We will dive into the technical heart of the rules engine, specifically our **prioritized** search strategies. You will discover how we manage the complexity of business contexts (Store, UID, Country, third-party type, etc.) to offer extreme granularity in controlling features and configuration values.

**Key points covered :**
* **Why ?** Shifting from rigid configuration to total autonomy for both business and technical teams.
* **How ?** Technical architecture, exception management, and conflict resolution strategies based on priority.
* **Impact :** Reducing operational costs, securing deployments, and accelerating In-Store innovation.

The day we stopped publishing Kafka events from our order API and why it strengthened our event-driven architecture
Wednesday May 27, 2026 09:00 - 09:30 CEST
This talk will present how we addressed the “dual write” issue we had in our Gifting Order Management solution between our database and our Kafka cluster, causing data inconsistencies and complicated error handling.

The answer ? A simplified version of the Outbox pattern—leveraging a Debezium connector to reliably decouple database writes from Kafka event publishing and using our Order table as the outbox table to simplify the solution.

This architectural shift resulted in a simpler, more robust Order API, eliminating Kafka-specific code and complex error handling. This loosely coupled architecture also offers consumer-driven business logic with easier extensibility.

Join this talk to learn how this architectural decision strengthened our event-driven architecture and discover the crucial details of configuring Debezium—including heartbeat and monitoring—to ensure stability and avoid database disk space issues.

Design and agentic pathways for Decathlon
Wednesday May 27, 2026 09:00 - 09:30 CEST
### Introduction:
The key theme is about how product designers can shape the future of an agent powered future for e-commerce. What new challenges do we face and how might we design experiences in this new reality? What new behaviours has this new technology opened up and how can designers use it to provide guardrails?

I want to cover the idea that shopping via AI might sound very cold and transactional, and in the context of Decathlon, that can count against us. Browsing products, becoming emotionally attached to new products and even physical stores themselves is a powerful connection we need to retain. It is a huge differentiator for us.

### The pathways:
Through the lens of three AI powered pathways, I want to explore the opportunities that have opened up for teams at Decathlon and how we might thrive in this new era.

* How do we improve our current experience with new AI tools available on our digital experience?
* What services can Decathlon reference to provide a richer, personalised product experience?
* How do we show up for our customers when they never visit Decathlon in a digital or physical sense?

### Loyalty and emotional connections:
AI use can place an extra layer between Decathlon and our customers, we need to make sure that loyalty is rewarded and is visible when customers use AI to shop.

* How can AI enhance the membership experience, inside and outside of Decathlon's experiences?
* How can we make sure that the repeatable, mundane tasks become automated where possible?
* At the same time, how can we design digital experiences where people do come to us to be inspired, to browse and fall in love with the brand and our products?

DECATHLON X ADEO - The great debate on the indomitable quality of application repositories
Wednesday May 27, 2026 09:00 - 09:45 CEST
The year is 26 after 2000. Digital repositories are fully operational and up-to-date. Well not entirely… Few small application repositories still hold out against some architectural qualities: discoverable, trustworthy, easily consumable, usefulness?
And life is not easy for these repositories: IDPix, LeanIX & Tangramix.

A great Decathlon - ADEO Leroy Merlin FR debate will be organized around these thematix to share best and bad practices:
- « Aren’t my data fresh? » : how we continuously insure the data freshness of our repositories?
- « I’m not fat, I'm just big boned! »: how do we add new data in our repositories and discard deprecated ones?
- « These Repos are crazy! » : how do we promote IT use cases on top of these repositories (Dev, Architecture, FinOps, IA…)?

DECATHLON X ADEO - The AI Ultra-Trail: Cross perspectives on the race for digital attention
Wednesday May 27, 2026 09:15 - 10:00 CEST
# Abstract:
LLMs (Large Language Models) like ChatGPT have entered the industry with a velocity that no retailer can ignore. In just a few years, usage has exploded to over 1 billion weekly users, with record amounts of capital pouring into the sector.
This represents a fundamental shift in how people interact with digital content—a revolution comparable to the advent of the Internet itself. A significant portion of human digital attention has shifted to this new medium, and business models are following.
We will discuss the different phases of this evolution and what it means for our brands Adeo and Decathlon. Where we think we are. How we believe it is about winning a war of attention in a new sales channels and what we are doing about it. We will also explore the potential risks that we have to mitigate along the way.

# Plan:
- Intro with the different phases of AI's impact on E-commerce. Look at the past to understand the future.
- Winning the attention battle - Why it matters. Some examples for our 2 brands (examples: GEO initiatives, ChatGPT App, POC with Mirakl, ....)
- Enriching our product sheets to promote discovery by LLMs (putting our product pages into perspective and their evolutions related to AI)
- AI Content and UGC
- Risk Analysis (we often don't talk about it enough, LLMs are a formidable opportunity but the path is filled with risks from brand and reputation to cost ).

# Bonus :
The last section is focused on using & benchmarking multiple AI Models (Claude, ChatGPT, Gemini, Kimi) to **imagine & design joint/common Product / Services / Tech Capabilities between Adeo & Decathlon in the future**

Less is More: Using AI to prove that doing less delivers more
Wednesday May 27, 2026 09:45 - 10:15 CEST
Four value streams, three and a half developers, all moving simultaneously. There was pressure to start everything — it looked like progress. But at the end of each sprint, delivered value was scarce. The data told a different story.

We ran an AI-assisted analysis of our historical flow metrics: WIP over time, lead time per story point, where epics actually got stuck. The pattern was clear — we had a systemic problem, not a capacity one. Starting earlier was making us finish later.

The fix was counterintuitive. We reduced the number of topics in flight, moved from individual domain ownership to team-based delivery, and realigned our backlog around collective throughput. The analysis showed a potential 2x improvement in lead time by reducing WIP — and early signals are promising.

We'll walk through the data that changed our thinking, the steps we took, what didn't go as planned, and what surprised us. Fair warning: the experiment is still running — no clean happy ending, just honest numbers and the reasoning behind every decision.

What you'll take away: a replicable approach to focused, team-based flow — and how to make "let's finish fewer things faster" a convincing argument.

Unlocking 42 Million Offers: How did a unified UI scale marketplace growth?
Wednesday May 27, 2026 09:45 - 10:15 CEST
In a marketplace with 17M+ products and 42M+ offers, every unpublished offer is lost revenue. But why is an offer not live? The answer used to be a mystery trapped in technical logs.
To solve this at scale, we didn’t just build a dashboard; we built a framework for clarity.
Join us behind our new Offer Management system to learn how we used the Pyramid of Failure to categorize user, business, and technical blockers. We’ll share the blueprint for building a single, scalable UI that serves diverse personas, empowering sellers with autonomy while providing tech teams one "Source of Truth" for debugging and investigation, and how this unified approach turned technical friction into GMV growth.

Digital Lean, the next step: How digital and lean thinking become the lever to turn complexity into continuous value
Wednesday May 27, 2026 10:00 - 10:45 CEST
Leroy Merlin Italia is completing a crucial phase of its digital transformation. Over the past years, we've built new platforms, adopted new tools, redesigned architectures, and invested heavily in digital capabilities. Along the way, we've collected powerful lessons learned and now we're putting them to work.

The next step is clear: **simplification and productivity**. We need to train our teams for process, not for product. We need to complete the human and mindset transformation, steering our squads toward cross-functional thinking and process efficiency, subtracting the superfluous instead of adding more. We need to leverage AI both to streamline business processes and to accelerate our tech and digital delivery (i.e. MVPs, prototypes, requirements, user stories, test cases) to unlock the potential of the solutions we've already built and to accelerate business outcomes.

In this post-onboarding phase, the real value that a digital team can bring to the organization is something that no single business direction can provide on its own: **a cross-functional, end-to-end vision of processes.** Business directions are by design and by vocation, focused on their vertical. That's their strength. But the digital team sits at the intersection of all verticals, and that unique position makes it the natural driver of process simplification, waste elimination, and horizontal efficiency across the entire value chain.

But here's what years of transformation taught us: **if you automate a mess, you just get a faster mess.** And nobody tells you that.

The Digital Lean Framework (DLF) is a framework that I conceived and designed with the support of my team, as a natural evolution of our purpose at Leroy Merlin Italia. It takes the core principles of lean thinking, born on Toyota's factory floors 70 years ago and applies them to digital, tech, cybersecurity, and organizational development. Not as theory, but as a proprietary operational method distilled from 20+ years of enterprise delivery and shaped by the lessons we've learned building, failing, and rebuilding in the field.

In this talk, I'll share:

- **Legge Zero**: why starting from technology to shape the process (instead of the opposite) is the original sin of digital transformation, and how to reverse it.
- **The 8 Digital Muda**: the invisible wastes killing your teams' productivity, from overprocessing and waiting to the most dangerous one: the **Perfection Trap**, a waste that doesn't exist in manufacturing but is devastating in digital.
- **A practical framework**: (VALUE → STREAM → CLEAN → FLOW → KAIZEN) to find and eliminate waste in any digital process from IT service delivery to product development.
- **Real results** from applying a first dry run of DLM within a bunch of use cases at Leroy Merlin Italia: what we found, what we cut, what improved, what assumptions we confirmed, what assumptions we destroyed, and what we're still learning.

This is not a talk about doing less. It's about doing what matters, with method, data, and relentless focus on value.

Giving hands to your AI: Building MCP servers with Java & Spring AI
Wednesday May 27, 2026 10:00 - 11:30 CEST
In 2026, "just chatting" with an AI isn't enough. We need agents that can act: query a database, trigger a deployment, or check real-time stock levels. Enter the Model Context Protocol (MCP)—the universal standard for connecting AI models to local and remote data sources.

This hands-on lab is a deep dive into building the "connective tissue" of modern AI. Using Spring AI, we will move beyond basic API calls to develop robust MCP Servers in Java. You will learn how to expose your existing business logic as "tools" that any LLM can discover and use securely. By the end of this session, you’ll know how to transform your Java applications into specialized plugins that give your AI the "hands" it needs to interact with your enterprise systems.

DBT LABS - The next phase of data platforms, picking the best compute engine for any task
Wednesday May 27, 2026 10:15 - 11:00 CEST
Depending on a single vendor for all data needs creates significant bottlenecks: vendor lock-in, unoptimized compute engines for specific workloads, and slow developer feedback loops. The next phase of data architecture demands a shift toward decoupled layers and flexible compute.

In this session, we will explore the future of data transformation built around open table formats and multi-engine processing. We will discuss how open formats like Apache Iceberg can turn Data Mesh theories into reality, while addressing current catalog challenges and where the ecosystem is heading next.

Finally, we will focus on enhancing the developer experience through local compute. We will run a practical demonstration where a Databricks/BigQuery dbt project is executed locally on DuckDB using automated SQL dialect translation. The result: zero cloud compute costs during development and lightning-fast iteration cycles for your data engineering teams.

A single source of truth for order tracking
Wednesday May 27, 2026 11:15 - 11:45 CEST
What happens when a customer checks the status of an order and finds different answers depending on the channel?
This question was the starting point of an investigation that revealed a bigger issue than it initially seemed: the same order could display different information in the app and on the web, regardless of whether it was placed through e-commerce or in a physical store. The outcome was predictable — customer confusion, increased Contact Rate, and a direct impact on NPS.

To understand the root cause, we initiated a **discovery process** that mapped the entire order journey across multiple customer touchpoints — app, web, telesales, email, and WhatsApp — while also diving into the systems that generate and distribute this information.
It quickly became clear that the challenge was not only technological, but about **orchestrating systems, channels, and teams to transform a complex ecosystem into a simple and reliable experience for the customer**.

Collaboration between squads enabled us to standardize information in the backend, increase transparency for the frontend, and evolve the order tracking experience — making it easier for customers to check order status, refund information, and in-store pickup details.

In the end, the goal is as simple as it is powerful: ensuring that customers can find a **single source of truth about their order**, no matter where they look. As a result, we aim to reduce Contact Rate, increase the app’s NPS, and decrease the number of abandoned payments.

In this talk, we will share the behind-the-scenes of this discovery process — and how technical and product decisions can directly transform the customer experience.

From individual contributor to management: How to become "Scalable" beyond code?
Wednesday May 27, 2026 15:30 - 16:00 CEST
You have spent years designing robust architectures, optimizing system performance, and automating everything that can be. As an Individual Contributor (IC), your impact is clear, measurable, and direct. But there comes a time when, to truly move the needle, you need to change your paradigm: what if your next scalability challenge wasn't technical, but human?

Moving from a technical expert role to a manager role should not be seen as a "promotion" up the hierarchy, but as a transition to a completely new profession where your success depends on the success of others. This is the story of moving from individual optimization to building a system capable of growing without you being a Single Point of Failure (SPOF).

Through this feedback from a former architect and open-source enthusiast turned Engineering Manager, we will explore the stages of this mutation:

* **Daily Impact:** How to redefine your "Definition of Done" when you no longer produce code?
* **Becoming Scalable:** Learning to delegate not to offload work, but to multiply the organization's impact.
* **Technical Legitimacy:** How to remain a credible peer without becoming your team's bottleneck.
* **Beginner Pitfalls:** Identifying common "bugs" for new managers (micromanagement, keyboard withdrawal, imposter syndrome).

This talk is for anyone questioning their future career path: should I remain an expert or switch to management? The goal is to provide concrete keys to successfully making the leap, understanding that management is ultimately about designing an architecture where humans are the most precious and complex components.

Your language is the new code: How CPQ turns your words into a working configurator
Wednesday May 27, 2026 17:00 - 17:30 CEST
Building a product configurator at Adeo has historically been a months-long endeavor: modeling compatibility rules, translating business constraints into code, endless test cycles… And evolving an existing rule? Days of work for the tech team.
With our CPQ (Configure, Price, Quote) project, **winner of the Adeo XP Awards 2026 in the Disruptive Innovation category**, we flipped this paradigm entirely. The only skill you need to use CPQ is the ability to write in your own language. A business expert describes a rule in plain words *"if the customer picks a floorboard wider than 15cm, only show compatible underlays"* and Gemini automatically generates the execution logic, along with a plain-language explanation to review before going live.
What used to take weeks now takes minutes. In this talk, we'll share how we built this AI pipeline (Spring AI + Vertex AI), the challenges we faced, and the lessons learned from a project where AI isn't a feature — it's the foundation.

On-Call at 3 AM: How does our AI resolve incidents before you do?
Thursday May 28, 2026 09:00 - 09:30 CEST
What if your best SRE was an AI capable of analyzing millions of signals in seconds?

In this session, I’ll show you how we built a "Home-Made" Incident Investigator to automate root cause analysis from the ground up. By leveraging the Model Context Protocol (MCP) to unify Datadog telemetry, GitHub source code, and ServiceNow tickets, our autonomous agent doesn’t just report issues—it investigates them.

We will dive into how the agent iteratively forms hypotheses, "peeks" into raw logs, and suggests code fixes the moment an alert fires. No more cognitive overload or endless manual digging during high-pressure outages. Come and learn how we are drastically slashing our MTTR (Mean Time To Recovery) by adopting an "Agent-First" approach to production operations.

Release Management as a Product: From Deployment Chaos to Controlled Value Delivery
Thursday May 28, 2026 09:45 - 10:15 CEST
Modern cloud-native platforms have dramatically improved how we build and deploy software.
Yet many organizations still struggle with fragmented releases, inconsistent promotions, limited traceability, and unclear ownership between CI, CD, and Operations.

This talk explores how Release Management can evolve from a technical mechanism into a true product capability.

We will cover:

• The gap between CI/CD tooling and real Release Management needs
• Common anti-patterns (pipeline-driven releases, manual promotions, hidden drift)
• The Digital Component approach
• Versioning, promotion flows, and rollback strategies
• The role of observability and governance
• How product thinking transforms Release Management adoption

Through practical examples from a large-scale platform environment, we’ll show how to move from “deployment success” to “controlled value delivery.”

If you think UI Design is still about moving a button 1 pixel to the left, I have some bad news: those pixels are dead. But here is the great news: Design has never been more alive.

In this keynote, we’ll explore the paradigm shift from "pixel pushing" to "Design orchestration." We will dive into how AI is transforming the UI Designer's role : moving from manual execution to strategic direction. Using real-world examples from Adeo’s CCDP, we'll see why the automation of our craft isn't a threat, but a liberation. Finally, we will discuss the "Human Moat": why empathy, ethics, and "habitant intuition" are the only things an algorithm can't simulate.

Change by design to change by default: Embedding adoption into digital platforms at ADEO
Thursday May 28, 2026 11:30 - 12:00 CEST
Digital transformation often focuses on building the right product, but success actually depends on adoption at scale.
At ADEO, with more than 120,000 collaborators across multiple countries and business units, launching a platform or product is only the beginning. Ensuring that solutions are understood, adopted, and embedded into daily operations requires a structured Change Operating Model.
In this talk, I will share how ADEO designed a “Change by Design” approach, integrating change management directly into the digital framework and delivery lifecycle.
We will explore how platforms, product teams, and business units collaborate to transform delivery into real impact, with the ultimate ambition of evolving from Change by Design to Change by Default.

Supply Chain operational performance through Agentic AI
Thursday May 28, 2026 12:15 - 12:45 CEST
This presentation covers the evolution of Supply Chain automation at Leroy Merlin Ukraine. How the decommissioning of our old version of Pyxis led us to an AI Agent-enabled workflows in *almost* one step.

- The Challenge: Balancing legacy system deprecation and an upcoming SAP migration while trying to eliminate the manual resolution of micro-errors (e.g., typos, conflicting addresses) that traditional automation cannot catch.

- The Breakthrough: Proving that AI Agents succeed where rigid algorithms fail. By mimicking human reasoning to clean up unpredictable user inputs, this architecture is designed to directly reduce our Manual Touch Rate (Exception Rate) and drive up our First-Attempt Delivery Rate (FADR).

- The Demonstration: A practical look at our "start small, explore patterns, test assumptions" philosophy, showing how AI handles the tedious exceptions so humans can focus on delivering value.

This is a perfect opportunity to address smaller BUs like ourselves with a viable, scaled-down approach to Agentic AI. The goal: eliminate the countless micro-errors that constantly drain Supply Chain teams already operating at full capacity.

From Bias to Breakthrough: A manager’s journey into neurodiversity
Thursday May 28, 2026 14:00 - 14:30 CEST
Diversity is often discussed in broad strokes, but what does it look like on the ground, in the middle of a noisy open space, when standard communication fails?

In this session, I will share the honest, unfiltered story of my collaboration with Hatem. When Hatem first joined as a contractor, the challenges seemed insurmountable: no eye contact, a total reliance on a job coach to communicate, and the sensory overload of a bustling tech environment. Fast forward two years, and Hatem is not just a permanent employee—he is a pillar of the team and a recognized expert across the organization.

We will walk through the heavy initial investment required to build trust and the specific adjustments—from daily 1-on-1s to "silent rooms"—that turned a difficult start into a technical breakthrough. You will discover how Hatem transitioned from a QA role to a QE (Quality Engineering) expert, mastering automation with the help of a structured mentorship model.

Key Takeaways:

- Beyond Soft Skills: How to adapt management for profiles that don't fit the "standard" social mold.

- The Mentorship Blueprint: Why the "Show once, let fly" approach works wonders for neurodivergent talent.

- Creating the Right Environment: Practical tips on handling sensory challenges (noise, open spaces) in tech offices.

- The ROI of Patience: Why investing time in neurodiversity leads to high-autonomy, high-impact technical experts.

GITHUB - From Autocomplete to Autopilot: How did AI rewire my life as a developer
Thursday May 28, 2026 14:00 - 14:45 CEST
In 2021, Copilot helped me finish lines of code. By 2024, I was chatting with it. In 2025, Context Engineering was the breakthrough. Now in 2026, I don't just talk to AI — I delegate to it.

Copilot CLI, Skills, agentic workflows, new models — I've gone from asking for help to handing over entire tasks, from scaffolding projects to opening pull requests, all in natural language. And it's not just me: at GitHub, our own product teams are using these same capabilities to ship faster and rethink how software gets built.

The shift goes beyond developers. Product managers, SREs, DevOps engineers — they're all becoming builders. It's no longer about writing code, it's about expressing intent.

In this talk, I'll show you what changed between 2025 and 2026, and how it turned me from a developer with a great assistant into a complete builder.


Note: In this session I will focus on the new features and primitives that have change my life, and GitHub's developers life too.

Hands-On: Domain Driven Design, from theory to practice
Thursday May 28, 2026 14:00 - 15:30 CEST
Is your domain code becoming complex, hard to maintain, and disconnected from real business needs? You keep hearing about **Value Objects**, **Aggregates**, and **Entities** at conferences but struggle to see how to apply them concretely?
This 1.5‑hour hands‑on workshop will demystify **Domain‑Driven Design (DDD)**. Forget abstract diagrams! We will start from a simple, collaborative business exploration (inspired by Event Storming) to let DDD tactical building blocks emerge naturally.
Together, we will incrementally code a small business domain in __Java__. Through **practice**, you will see which concrete problems a Value Object or an Entity solves, how the Aggregate safeguards data consistency.
Whether you are a curious developer or looking to better structure your applications, this workshop will give you the keys to move from theory to practice and start applying DDD in your projects as of tomorrow.

Women in software engineering: what gives?
Thursday May 28, 2026 14:45 - 15:15 CEST
With the advent of the age of AI software has never played such an outsized role in our daily lives and yet women only account for a small minority of software engineers. This is especially disheartening given that many - but not all - of the first software engineers were women (Ada Lovelace, Katherine Johnson, Margaret Hamilton, Grace Hopper, ...).

This talk aims to stay away from dogma or political posturing, instead focusing on explaining why more women aren't software engineers and proposing concrete, tactical and doable solutions.

The first part of the talk recounts the stories of some of the pioneers who built flight control systems for the Apollo mission, lamenting that their stories aren't more widely known.

I then use those examples to contrast with the current state in our Industry where female developers only account for a minority of software engineers.

I'll then give an overview of why I believe more women don't become software engineers, briefly explaining why this is the case.

I'll also share why some of the women who become software engineers eventually leave our Industry and what we can do to retain them.

Finally, I'll conclude with concrete actions we can all take in order to increase the amount of women in software engineering.

This is a tentative/more detailed outline of the talk:

Introduction: the pioneers.
Ask attendees to look around them, notice how little women are in the room.

This wasn't always the case and we have many examples of women who've made massive contributions to software engineering: from Ada Lovelace to Grace Hopper.

How we got here.
The first part of the talk uses a data driven approach to describing the problem at hand, focusing on how many women are developers.

Why we got here: women in STEM
After underlining the fact that education is key and that only a small amount of women pursue an education in STEM I'll briefly explain why that is.

Adding insult to injury: female software engineers in the workplace
I'll then continue on by explaining that even when they are software engineers a lot of women end up leaving our Industry despite haven chosen a career path in software engineering.

What can be done about it?
Finally, I'll focus on the possible solutions we as individuals can implement in order to increase the amount of women who become software engineers and make our teams more diverse. I'll focus on the power of mentorship, the importance of retaining the female software engineers on your team by fostering a culture of respect, empathy and excellence.

AI and software are transforming our lives and shaping how we view, interact with and perceive the world; and yet software engineering teams are way too often stacked with men. This talk isn't about political posturing or gimmicks, it's about explaining how we got here, providing data on what the current state of affairs is, why this problem matters (importance of building diverse teams) and what can be done to solve it. The solutions proposed don't include quotas or political dogma but instead focus on concrete solutions like building role models, fostering mentorship and encouraging girls to pursue STEM education.

Beyond Intuition: AI-Assisted Metrics From Jira and GitHub to Diagnose Team Health
Thursday May 28, 2026 15:30 - 16:00 CEST
Management decisions about engineering teams too often rely on incomplete signals — sprint velocity, subjective updates, and what surfaces in status meetings. But the data to make better decisions already exists: in your Jira and GitHub, waiting to be connected.

We used AI-assisted analysis to extract flow metrics from Jira and DORA indicators from GitHub — and what emerged was a picture no one had seen before. Trends in change failure rate, rework patterns, and team load revealed systemic issues that weren't showing up in any dashboard or review meeting. The data didn't just confirm suspicions — it reframed the conversation entirely.

What followed was a structured change process: workshops grounded in evidence, renegotiated team agreements (Definition of Ready), and a shift in engineering practices — driven not by management mandate, but by shared understanding of what the numbers were saying.

This talk is for managers who lead engineering teams and want to move from intuition to insight.
You'll learn:

- How to surface flow metrics from Jira and DORA indicators from GitHub
- What patterns signal team stress, quality erosion, and instability — before they become crises
- How AI lowers the barrier to analysis: no special skills required
- How to use metrics to drive change conversations — not performance evaluations

The experiment is still in progress. We'll share early signals, honest lessons, and what we'd do differently.

At conferences, we usually showcase our best products with elegant interfaces, smooth user journeys and impressive adoption rates.
But if we're honest, digital products are still making the same design mistakes again and again.

I want us to remind together the worst of UX: confused users, friction points at every steps, leading us to wrong decisions. Invisible actions, misleading buttons, dreadful forms,... We all know that this is bad so why do we still keep seeing them online?

Let's explore through funny examples, the strange, the surprising or deceptful designs that made us yell altogether "Bad UX!"
Because good experience is most of the time not about innovative patterns but about preventing and avoiding obvious mistakes, we can questions ourselves about quality of the experience we want to deliver to our users.

Is English the new hottest programming language? Introducing Spec-Driven-Development with AI
Thursday May 28, 2026 16:00 - 16:45 CEST
Ever since vibe-coding hit the scene, you might think knowing how to code is old news for building apps thanks to AI. But let's be real, some of us who dove in got burned: hallucinations, performance and security issues, messy code, and the final product not quite matching the initial idea.

What if there was a way to **get the best of both worlds**? To boost efficiency leveraging AI while being 100% confident when pushing to production?

We chose **Spec-Driven Development** using **SpecKit** to build an application we deployed with total confidence, using **English** (and some French\!) as our main "programming" language\!

In this talk, Christine (Product Manager) and Julien (Staff Software Engineer) will reveal:

* **The "state of the art"** in this space and where the industry stands today.
* **What is Spec-Driven-Development**, in a nutshell
* How AI helped us build the *right* software by supporting **both the PM and the developer**.
* **Ensuring code quality** while dodging nasty surprises.
* **Real-world struggles** and the pitfalls you’ll want to watch out for.
* **Where we go from here** \- the areas we're still refining and what we've yet to solve.

The Hidden Cost of Intelligence: From Cloud Transparency to Sustainable AI
Thursday May 28, 2026 16:15 - 16:45 CEST
Artificial Intelligence is often seen as a virtual, weightless force. Yet, its environmental footprint—from GPU intensive training to daily inference—is very much physical. As Decathlon and Adeo accelerate their AI integration, a crucial question arises: Can our innovation be truly "forward-thinking" if it isn't sustainable?

In this session, I will take you behind the scenes of a 2025 Proof of Concept that bridges the gap between raw compute power and ecological responsibility. We will explore how leveraging cloud environmental telemetry allowed us to establish the first reliable & actionable metrics for AI environmental impacts.

Key takeaways from this talk:
- The Foundation: How cloud-native monitoring tools serve as the "entry point" for measuring AI impact.
- The 2025 POC: Real-world feedback on integrating environmental metrics into the AI lifecycle.
- Actionable Strategies: Moving from "Carbon Awareness" to "Concrete Environmental impact limitation" without sacrificing model performance.
Let’s stop treats AI as a black box and start building an architecture that respects both our business goals and our planet.

How to turn millions of digital user interactions into instant business signals
Thursday May 28, 2026 16:15 - 16:45 CEST
Imagine if we could understand a user’s intent while they are navigating.Not just what they click but what they are trying to achieve.
Are they looking for inspiration? Designing a project?Are they exploring broadly, or focused on a very specific product universe?
If we could detect that in real time, we could adapt the experience instantly, surfacing the right contents and products among the millions we have.
That’s the promise of clickstream: turning user behavior into signals of intent for a continuously experience improvement

In this session, we will present how clickstream captures and streams millions of user navigation events per day in milliseconds timeframe and how these events are enriched and transformed into meaningful signals and aggregates to empower user journey.
