hi, I'm léo 👋
About
I'm a product engineer and freelance developer based in Lyon and Paris. Currently a data scientist at 
BPCE, building AI tools for audit, and a student at 
Epitech.
As a freelancer, I co-develop 
Wondday, a family outings app used by more than 90,000 people. I also built 
Blocker, which blocks distracting websites on macOS, and 
Stremlist, which brings your IMDb watchlist to Stremio.
I write about what I learn. Beyond code, I love 
sports, 
travel and time with 
friends. For a project, send me a short brief.
