About Sylvain

I've just published my new book: "AI: The Hunt for Intelligence - Beyond the Hype and Fear"
Available on Amazon.

For three decades, I’ve helped organizations make smart decisions in software — and more recently, in AI. My work focuses on clarity: identifying real opportunities, defining the right approach, and guiding leaders through decisions that matter.

I create Complex Ai Agents Architecture for businesses. LangFlow, LangGraph.

Many SMEs and startups want to adopt AI or accelerate their software development, but face the same questions:
• Where do we start?
• Is this a good case for AI?
• Should we build in-house or outsource?
• What team structure will deliver reliably and fast?

This is where I step in.

My background spans hands-on software engineering, leadership, global delivery, and AI research. I hold a PhD in symbolic AI, have run software companies for 23 years, and understand both the technical and business sides of innovation. I work with executives to assess feasibility, define strategy, and shape a realistic plan before any investment is made.

I am happy to travel for work and do work onsite.
