About this gig

Python script crashing, giving wrong results, running slowly or just messy? Send the code and the error. I find the cause, fix it and prove the fix with a test.


What I can fix:

- Tracebacks and exceptions in scripts and small apps

- Wrong output and logic bugs

- Slow scripts and memory problems

- Dependency and version errors (pip, virtual environments, Python upgrades)

- Issues in PySide6/Qt, pandas, requests and Flask code

- Clean-up: docstrings, type hints, structure


What you get: the fixed code, a plain-English note on the root cause, a regression test where practical and a summary of what changed.


Not included: full rewrites (ask for a custom offer), bugs that only show on your live servers, and languages other than Python.


I use modern development tools, including AI-assisted coding, automated tests and a manual review of every delivery.

I'm a software and test engineer who builds practical Python tools: automation scripts, PDF and Excel report generators, desktop apps (PySide6, PyQt, Tkinter), API integrations, bug fixes and automated tests. I focus on reliable, well-tested, clearly documented work with plain communication from first message to delivery. I use modern tools, including AI-assisted coding, plus automated tests and a manual review of every delivery. Send me your file, error message or idea and I'll tell you honestly whether I can do it and what it will cost.
