I will fix python backend bugs fast


About this gig
Is your Python backend failing, returning errors, or behaving incorrectly?
I will diagnose and fix bugs in Python, Django, Django REST Framework, FastAPI, or Flask projects.
I can help with:
Python exceptions and tracebacks
Broken REST API endpoints
Authentication, JWT, and permissions
PostgreSQL, SQLAlchemy, and migration errors
Docker and environment issues
Third-party API integration bugs
Async, Celery, and Redis problems
Slow queries and API performance
Tests and production startup errors
The Basic package covers one small, isolated issue delivered within 24 hours. Multiple or complex problems require the Standard, Premium, or a custom offer.
Please contact me before ordering. Send the traceback, logs, expected behavior, relevant code, and instructions for running the project. You will receive the corrected source code and a short explanation of the fix.

FAQ
What counts as one isolated bug?
One isolated bug is one clearly reproducible issue, such as a traceback, broken endpoint, startup error, failed database operation, or small logic defect.
What do you need before starting?
Please provide the source code, error message or traceback, reproduction steps, expected behavior, actual behavior, and instructions for running the project.
Is every order completed within 24 hours?
The 24-hour delivery applies only to the Basic package and one small isolated issue. Complex or multiple bugs require a longer package or custom offer.
Will I receive the corrected source code?
Yes. Source code is included in every package, together with a short explanation of the identified problem and implemented fix.
