About this gig

Your Python app throws errors, returns wrong data or got slow? I find the cause and fix it properly, not with a workaround.


I work daily with Python, FastAPI and PostgreSQL as lead engineer of an analytics platform, so I know where these apps usually break.


What I fix:

  • Crashes, tracebacks and 500 errors
  • Wrong or missing data from the database
  • Slow endpoints and heavy SQL queries
  • Broken dependencies, Docker or environment issues
  • Async, validation and serialization problems (Pydantic)


What you get: the fix, a short note on what caused the problem, and how to avoid it next time.


Send me the error message and access to the code (repository or archive) before ordering, and I'll confirm whether it fits the package.
