Crafting performant web experiences —
frompixeltoAPI.Antananarivo, Madagascar
Developer, maker,
and lifelong learner.
Fullstack developer based in Antananarivo, Madagascar, with over 4 years of experience crafting performant web experiences from pixel to API. I specialize in React ecosystems, working with TypeScript, Next.js, and modern frontend architectures.
My backend expertise includes Node.js, Express, and NestJS, allowing me to build complete, production-ready applications. Throughout my career, I've had the privilege of working with diverse teams — from micro-frontend architectures to real-time collaborative applications.
When I'm not coding, I'm actively involved in the tech community, mentoring young developers as a Tech Lead for GDSC ISPM. I believe in open knowledge sharing and the power of building things that matter.
