About

Senior Platform Engineer, problem solver, and curious tinkerer

The Story

Born in 80s France with a dad in IT, no wonder I got into computers. I started programming at 7 because that’s all you could do with them once you played all the games you had.

I consider myself lucky to have witnessed tech change so much in my lifespan. It kept me on my toes and forced me to always be learning. And to be fair, I just love to do that.

My career path is not the typical one: I got degrees in network engineering but my first job was where many engineers never go: support. Mainly because the IT job market was a bit rough in France at the time. Anyway, that journey from support to ops to architecture to platform - it gives me a different perspective on what we should strive to achieve with tech. And a lot of empathy for other people too.

The thread throughout has always been curiosity and problem-solving. That’s probably what kept me in this field for the past 20 years or so.

What I Do Now

I’m a Senior Software Engineer on a platform team at Doctolib, focused on improving developer experience across all our services. My operational background - fielding support calls, years of being on-call, and managing production systems - shapes how I think about the tools we build. I’ve felt the pain, so I know what actually helps.

Beyond the Keyboard

Home lab enthusiast: I have way too much Raspberry Pis scattered around the house running various experiments, also a 18U rack in the basement for the “necessary” core house infra. Currently writing this from my NixOS laptop.

Security tinkerer: From cracking passwords as a kid to bug bounties as an adult, I’ve always been drawn to security puzzles. CTF challenges scratch that itch when time allows.

Sports: Competitive discgolf (still a noob on the verge of breaking 800 rating), recreational basketball. I’ve also done football, judo, tennis, American football, baseball, and weightlifting over the years.

Outdoors: Hiking and hammock camping when I can escape the screen.

Puzzles: Escape rooms, armchair treasure hunts - the same problem solving mindset that drove the early hacking drives this too.

Reading: Always have multiple books going.
