Professional profile

Product-oriented fullstack development

Fullstack Developer and Systems Engineer with 2+ years of experience building end-to-end web and mobile applications. Strong in frontend with React, Next.js, TypeScript, and TailwindCSS, and cross-platform mobile with Flutter/Dart. Backend experience with NestJS, Prisma, and PostgreSQL for REST APIs, authentication, and data persistence. I have delivered employment platforms, e-commerce, SaaS, and MVPs for clients in Colombia, Latin America, and Australia.

How I add value

  • Web frontend with React, Next.js, TypeScript, TailwindCSS, React Query, SEO, and i18n.
  • Mobile with Flutter, GetX, Clean Architecture, and Firebase (Auth, Firestore, Storage).
  • Backend with NestJS, Prisma, PostgreSQL, REST APIs, and JWT authentication.
I work across web and mobile frontend in parallel, applying clean architecture and fast delivery supported by modern tools like Cursor.
