Backend & Cloud · Tech Lead · Toulouse, France

Backend & cloud engineer

Seven years of experience on high-volume, business-critical systems — currently tech lead on Airbus Skywise.

Most of the code I write is private. What I can show are my decisions: each case study below documents a context, a constraint, and the technical choices that followed. It is a more faithful picture of how I work than a list of technologies.
