About this gig

Is your Python backend slow, broken, or throwing errors you can't figure out?

I've spent 3+ years building and debugging Python backends FastAPI, Flask. I know exactly where things break and why.

What I fix & optimize:

Bug Fixing

  • Unexpected errors & exceptions
  • Broken API endpoints
  • Authentication & authorization issues
  • Database query errors
  • Third-party integration failures

Performance Optimization

  • Slow API response times
  • N+1 query problems
  • Database indexing & query tuning
  • Memory leaks & high CPU usage
  • Async/await implementation

Code Quality

  • Messy, unreadable code cleanup
  • Security vulnerabilities
  • Refactoring & restructuring
  • Adding proper error handling


Tech I work with: Python · Django · FastAPI · Flask · PostgreSQL · MySQL · SQLAlchemy · Redis · Docker · REST APIs


Before placing an order send me a message first. I'll review your issue and confirm I can solve it. No wasted time, no guessing.
