About this gig

I will debug and optimize your Python backend so it runs faster, more stable, and easier to maintain.

If you have:

  • 500 errors, 404s, or crashes in Django/FastAPI/Flask
  • slow API responses or database queries
  • messy or hardtoread backend code

then I can help.

What I do:

  • Locate and fix bugs in your Python backend (Django / FastAPI / Flask).
  • Improve performance by optimizing queries, loops, and hotspot functions.
  • Clean up code structure, remove dead code, and add useful comments.
  • Suggest small architecture improvements (e.g., caching, background tasks, better separation of concerns).
  • Deliver: working code, bug report, and performance notes.

Tech stack I use:

  • Python (3.83.12)
  • Django / FastAPI / Flask (write which you actually use)
  • PostgreSQL / MySQL / SQLite
  • Optional: Redis, Celery, Docker (if you use them)

How we work:

  1. You send your project (repo / code / requirements).
  2. I analyze issues and send a short report.
  3. I fix bugs and optimize performance.
  4. You review and request revisions.
  5. Final delivery.

If you want me to debug and speed up your Python backend, order now and describe your project in the requirements.
