About

5th year at Epitech, after a year abroad in Brazil. 5 years of practice, 18 months of cumulated internships (startups, scale-up, agency), several projects shipped to production.

My comfort zone is modern fullstack web (Svelte, Nest). But what I really enjoy is touching the whole stack — from low-level backend to Kubernetes orchestration. I work best when I can see the full system.

I speak French, English and Portuguese. Comfortable managing a client directly or integrating into an existing tech team.

Available 2 days a week or more, in France or remote.
