About me

I'm a software engineer with a Master's degree in Information Systems and Web from the Higher School of Computer Science (ESI). Over the last two years I've worked as a full-stack developer in a digital agency, shipping React and Node.js applications for multiple clients, and as a research intern at INRIA in France, where I built developer tooling with a strong focus on testing and design patterns.

I moved to Germany on a Chancenkarte and I'm looking for my next role as a junior full-stack or frontend developer. I'm currently learning German and I work comfortably in English and French.
