I will fix your python app


About this gig
Got a bug that is blocking your application or wasting hours of development time? I can help.
I will investigate, debug, and fix issues in your Python backend, API, or web application with a focus on finding the actual root cause not just applying a temporary workaround.
I can help with:
- Python, Django, Django REST Framework, and FastAPI
- API errors and integration issues
- Database and ORM problems
- Authentication and authorization bugs
- Performance and backend logic issues
- Failing tests and unexpected behavior
- Refactoring code related to the issue
You will receive clean, maintainable code and a clear explanation of what was fixed.
For complex issues, I also offer root cause analysis and focused code review as optional extras.
Please contact me before ordering if the issue involves a large codebase, multiple services, or an unclear scope. This helps me evaluate the problem and recommend the right package.
