About Usman Ali

I build web and mobile applications that are fast, clean, and built to last. With 7+ years of full-stack experience, I specialise in Angular and React; turning your ideas or Figma designs into production-ready apps with solid architecture underneath.
Whether you need a web app from scratch, a new feature on an existing platform, or a mobile app with React Native, I handle the full journey; frontend, backend (Node.js), and database (PostgreSQL, MongoDB).
Based in Valencia, working with clients across Europe.
