Full-stack developer based in Catalonia, Spain. I build production-ready web applications with a focus on server-side rendering, design systems, and industrial-grade tooling.
My work spans warehouse management systems, e-commerce storefronts, reusable SCSS/TypeScript libraries, and multilingual personal sites — all engineered around clean architecture, SOLID principles, and strong typing.
