Sobre este Serviço

Is your MERN stack application throwing errors you can't solve? I specialize in diagnosing and fixing bugs across the full React, Node.js, Express, and MongoDB stack fast, cleanly, and without breaking your existing features.

What I fix:

  • React component errors, state management bugs, hook issues
  • Node.js and Express API failures, route errors, middleware problems
  • MongoDB connection issues, query errors, schema validation problems
  • JWT authentication bugs and session handling errors
  • CORS errors, deployment issues, environment configuration problems

What you get:

  • Root cause explanation (not just a fix you'll understand what went wrong)
  • Clean, commented code
  • Test confirmation that the fix works
  • No damage to existing features

I have built full-stack applications using React, Spring Boot, PostgreSQL, and JWT authentication. I understand how these systems connect and where they break.

Send me your error message or GitHub link and I'll review it before you order no obligation.
