About Me

I'm a full-stack developer who transitioned from hotel management and hospitality into tech. That background gives me something most developers don't have — I understand both the technical and human side of building products.

I build full-stack web apps with Ruby on Rails and Next.js, integrating APIs and AI into real projects that are live and used by real people. Open source contributor to Kaminari, ruby-openai and simple_form, Ruby gems with millions of downloads. I'm currently open to full-stack developer roles — remote or France-based.
