About me

I'm a Site Reliability Engineer and backend developer with 15+ years of experience building infrastructure and backend systems at scale. My career has taken me from crafting open-source OpenStack tooling at Objectif Libre to engineering automation for thousands of bare-metal servers at Amadeus, architecting cloud infrastructure at Airbus, and most recently developing AI-powered search and customer onboarding platforms at Symphony.

I thrive at the intersection of software engineering and operations — writing the code that keeps systems reliable, scalable, and fast. Outside of work, you'll find me contributing to open source, exploring new technologies, or enjoying the outdoors around Toulouse.
