About

Full-stack developer based in Paris, working across backend and frontend to build analytics and production-grade applications. I enjoy designing algorithms, integrating APIs, and shipping reliable features with clean architecture.

I’ve contributed to healthcare and energy awareness platforms, implemented security improvements (MFA), and led a small team to deliver a mobile e-learning product. I also build AI-driven tooling (speech, lip sync, and music generation) and automate workflows using modern web and automation stacks.
