However, the ecosystem is still highly uncertain; the surrounding technologies (ADK, LangGraph, CrewAI, etc.) are very young. Ultimately, picking one right now feels more like a gamble than an informed choice. **So, what solution would allow us to...

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...
