Hi, I'm
I build systems, break them on purpose, and write about what I learn.
Featured Project
Where I go deepest on distributed systems — and the one thing here you can break yourself.
Live demo
RaftLock
Raft consensus from first principles — five clean layers, custom storage engine, simulation-tested. Kill two nodes and watch the cluster recover, live.

Work Experience
Every move was deliberate. Follow the line — from a student research paper to safeguarding planet-scale systems at Google.
Where it starts
At 11, a stray "View Source" pulled me in — I rebuilt Google Search in raw HTML and didn't stop. Lycée Louis-le-Grand — France's most selective high school — then years of classes préparatoires — pure mathematics, physics, and logic. The hardest years of my life, and the most formative. I kept building through all of it.

Master's from ENSEA, two AWS internships behind me, a full-time offer on the table — I chose to come home to Paris instead. Three months of self-taught iOS later, I had the role.
