I will debug and fix your fastapi or python backend errors
Miraj
About this gig
I fix broken FastAPI and Python backends failing endpoints, wrong status codes, database connection errors, authentication issues, and bugs that are hard to trace on your own.
What I deliver:
- Root-cause debugging, not just a quick patch I explain what actually broke and why
- REST API fixes with proper request/response validation (Pydantic)
- PostgreSQL/SQLAlchemy connection and query fixes
- JWT authentication and route-protection issues resolved
- Clear explanation of the fix so the same bug doesn't come back

Hi! I'm a Python and FastAPI developer focused on building and fixing backend systems that work. I specialize in REST API development, PostgreSQL integration, authentication, and debugging broken backends — wrong status codes, failing database connections, and API errors. I'm currently building GigRadar, a FastAPI job aggregation platform, so I work in this stack daily. I also have hands-on experience in web scraping and automation, having delivered a production data extraction tool with deduplication and error handling. Clear communication and clean, working code — every time.

FAQ
What info do you need to start?
Your error message or stack trace, a short description of what's not working, and access to the relevant code (repo link or files).
What if the bug turns out to be more complex than expected?
: I'll message you before continuing, explain the scope, and we can adjust the package or agree on extra work ,no surprise charges.
Do you only fix bugs, or can you also build new features?
This gig is focused on debugging and fixes. For new API development or full backend builds, message me first , I can scope it separately.
Do you need access to my server or database?
Only if the bug requires it. Many issues can be fixed by reviewing code and logs alone — I'll tell you exactly what I need before starting.
