I will fix bugs and errors in your python fastapi app or rest API
Rushauti B.
About this gig
Stuck on a Python or FastAPI error? I will find the root cause, make a focused fix in your existing code, and explain what went wrong.
What I can help with:
- Python exceptions, tracebacks and logic errors
- FastAPI endpoint problems: routing, status codes, validation errors
- REST API request/response issues: payloads, JSON, headers, query params
- Pydantic validation and data-parsing bugs
- File upload and data-import bugs
- Data-processing bugs, including SQL query issues
What you get:
- A focused fix to your existing code
- A short written note on the root cause and what I changed
- Steps to check the fix on your side
What I need from you:
- The code or repository access
- The full error message or traceback
- Steps to reproduce, plus expected vs. current behavior
Not included: full rewrites, new features, server or cloud infrastructure, security audits or penetration testing.
Please message me before ordering so I can review the issue and confirm the right package. I can't guarantee a fix before seeing the code.

FAQ
Which package should I choose?
Basic is for one clear bug. Standard covers up to 3 related bugs or one small API issue. Premium is for several related issues in one area of your app. If you're not sure, message me the error and I'll suggest the right one.
Can you work with my existing code?
Yes. This Gig is for existing Python and FastAPI projects. I make focused changes to your code instead of rewriting it, and I explain every change I make.
What if my issue is bigger than the package I ordered?
If the problem turns out to be larger than your package, I will tell you before doing extra work and explain the options, such as upgrading the package or a custom offer. Nothing extra is added without your agreement.
Can you guarantee the bug will be fixed?
I can't promise a fix before seeing the code. That's why I ask you to message me first with the error and the relevant code, so I can confirm the issue is something I can solve within the package.
Do you fix server, deployment or security issues?
No. This Gig covers bugs in application code: Python, FastAPI, REST API logic and SQL queries. Server setup, cloud infrastructure, security audits and penetration testing are not included.
