👋 Hey, I'm Carlos

Frontend Developer focused on building production-ready React applications with strong TypeScript foundations, clean UI architecture, and real backend integrations.

I enjoy working on systems that are actually used — where maintainability, clarity, and user experience matter.

🧠 Core Focus

  • Building scalable React frontends
  • Designing clean component and UI architecture
  • Integrating real APIs with proper auth flows
  • Writing predictable, type-safe frontend code
  • Refactoring as products evolve
