About this gig

Your API is throwing errors and you need someone who can actually find the root cause.


I fix backend problems that have you stuck:


What I fix:

  • 500 errors and unhandled exceptions
  • Database query failures (N+1, timeouts, deadlocks)
  • Authentication and authorization bugs
  • Memory leaks and performance issues
  • Third-party API integration failures


How it works:

  1. You describe the problem and share relevant code/logs
  2. I diagnose the root cause
  3. I fix it and explain what went wrong
  4. You get a working system + knowledge to prevent recurrence


My guarantee:

If I can't identify and fix the issue, you pay nothing.


Delivery:

Most fixes completed within 24-48 hours.


Message me with your error message or problem description. I'll tell you if I can help before you order.

Backend developer specializing in Spring Boot, REST APIs, and fixing broken production systems. I've spent 6+ years building and repairing backend applications, AI-powered document processing, and API architecture that scales. What I actually do for clients: • Build REST APIs from scratch (Spring Boot + PostgreSQL) • Fix 500 errors, memory leaks, slow endpoints • Third-party APIs • Migrate monoliths to microservices I don't just write code, I solve the specific problem that's costing you time or money. Available for both new builds and rescue missions. Message me with what you're facing.
