About
I'm a software engineer with a background in data science, focused on building practical products that leverage AI and modern web technologies.
After years of research and experimentation in the data world, I transitioned to full-stack development to create tangible solutions. I believe the future lies in the thoughtful integration of AI into everyday tools.
Currently based in Nice, working with Vue, Nuxt, TypeScript, and AI APIs.
