I will fix a python fastapi or django backend bug

Is one Python backend issue blocking your release? I will diagnose and fix a clearly reproducible bug in an existing FastAPI, Django or Python service.

You receive a focused code change, a concise explanation of the root cause, and verification appropriate to the selected package. I work carefully with existing code and preserve unrelated behavior.

Suitable issues include API errors, validation problems, failing endpoints, database integration defects and regressions with clear reproduction steps.

Please message me before ordering if the cause is unknown, the project is large, or production access may be required. New applications, major redesigns, malware, credential bypasses and unauthorized access are not part of this Gig.
