FAQ
What information do you need to start fixing my bug?
To get started, I need a clear description of the issue, the exact error message or traceback you are seeing, and the specific file where you think the problem lies. Screenshots or a brief screen recording are also very helpful!
Do I need to provide access to my entire codebase?
Ideally, yes. Having access to the repository (GitHub/Bitbucket) or a ZIP file of the project allows me to see the full context and ensures the fix doesn't break other parts of your app. If you prefer, we can also work via a TeamViewer/AnyDesk session for small logic fixes.
Can you fix issues with FastAPI and Flask as well?
Absolutely. While I specialize in Django, I am an expert in the entire Python ecosystem. I can debug FastAPI asynchronous issues, Flask routing errors, and general Python automation scripts (Pandas, Selenium, etc.).
Will you help me deploy the fix to my server
My Basic and Standard packages include the code fix itself. If you need help deploying the changes to AWS, Heroku, DigitalOcean, or a VPS, please select the Premium Package or add the "Deployment Support" extra.
My migrations are stuck or messy. Can you fix them without data loss?
Yes. I am experienced in handling complex Django migration conflicts. I will carefully analyze your database schema and migration history to resolve the "bloat" or "circular dependency" without compromising your existing production data.
Do you write tests for the bug fixes?
For the Standard and Premium packages, I include basic unit tests for the fix to ensure the bug never returns. If you have an existing test suite (pytest/unittest), I will make sure the new code passes all checks.
What if you can't fix the bug?
In the rare case that a bug is tied to a third-party service limitation or a platform issue beyond Python's control, I will explain the situation clearly. If I cannot provide a working solution or a viable workaround, I will offer a full refund.
