About this gig

Is your Node.js or Express.js backend throwing errors, crashing, or behaving unexpectedly? I will find and fix the issue fast.

With 4 years of professional backend development experience, I have debugged and resolved issues in production-grade systems including REST APIs, authentication flows, database queries, and microservices.

What I can fix:

  • Node.js and Express.js errors and crashes
  • REST API issues (broken routes, wrong responses, CORS errors)
  • JWT authentication and authorization bugs
  • Database query errors (MySQL, PostgreSQL, MongoDB)
  • Async/await and Promise issues
  • npm package conflicts and dependency errors
  • Environment and configuration issues

What I need from you:

  • Your code via GitHub link or zip file
  • Description of the bug and steps to reproduce
  • Error logs if available

I will fix the bug, explain what caused it, and deliver clean working code. If I cannot fix it, you get a full refund.

Message me before ordering happy to discuss your issue first.
