Senior Full Stack Engineer — Next.js / TypeScript / Python | AI & Mission-Critical Systems | 4+ yrs @ SYSTRAN & CEA | Remote Worldwide
I'm a Senior Full Stack Engineer based in Paris, France, with 4+ years of experience building high-scale web applications in mission-critical environments — AI platforms and aerospace.
At SYSTRAN by ChapsVision, I lead the development of an industrial NMT (Neural Machine Translation) platform: I architected a full migration from React to Next.js (App Router), delivering +40% page load improvement and +35% Core Web Vitals score. I also design async Python/Flask workflows for processing large bilingual datasets and maintain 99.9% uptime across AWS environments via Docker and GitLab CI/CD.
Previously, I spent 3 years as Software Lead at CEA (French Atomic Energy Commission) on the SVOM astrophysical satellite mission — building a real-time telemetry ingestion API (Python/Flask), an interactive React dashboard for millions of data points, and a PostgreSQL schema optimized for sub-second queries on massive historical datasets.
