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.

Join us to learn how to move beyond the hype and embrace a development process that we found smart, effective, and production-ready\!
