Honfleur at night

I build products, from the first prototype to production.

Honfleur, Normandy

20+ years of shipping software. GenAI since 2023: at AWS, at Betclic and in my own products.

What I do best: take a business problem, find the architecture that fits, and build it, from the first prototype to production. At AWS I did it 30+ times with customers, 2 to 6 weeks each. Before GenAI, I was a cloud architect for hundreds of AWS customers.

Today at Betclic, as Staff GenAI Solutions Architect, I review GenAI projects, build prototypes with product teams and lead MCP adoption.

I do it for myself too: StreetLens and Back From My Trip, two products I co-founded, both live.

Back From My Trip

Trip reports that end with one question: would I go back? LLMs moderate every report and find the places. They never write a word.

My other passion. I shoot the places I travel to, mostly on my iPhone now.
