Learning by doing for 40 years
It started with Maths. Then code, taught to myself. Then consulting, energy, data, AI — 20 years navigating between business and technology at places like Engie, where I currently lead Digital & Data for Large Customers.
But titles don’t tell the whole story. What drives me is curiosity — and the need to actually build things to understand them.
How does the brain work? Take a neuroscience course, then build an app. Chess? Hours of YouTube, 10,000 games. AI? Get Claude Code and start building. IPAs? A website with a terrible pun for a name. And that’s just what fit on this page.
I also write — by hand, not by AI. About what I learn, what I read, what I think.

Stories from other projects
Drift
5,500 lines compressed into 164. One file, one input, one more try.
IPA and vibecoding
Three successive AI tools for a beer encyclopedia hallucinated from A to Z — and what remains, in the end, is the joke.
Bet on time
Twenty years wanting to redo the Million Dollar Homepage with time as the canvas. Two objects, and the same AI that buried both.
Tinkers
Small things with no big ambitions, worth a passing try.
