I will fix bugs and errors in your python script or app
Valentin A
About this gig
Your script worked yesterday and today it doesn't. Or it works on your machine and dies on the server. Or it runs fine until row 4,000.
I find the cause and fix it, in Python.
WHAT I FIX
- Exceptions and tracebacks you can't get past
- Code that broke after a Python or library update
- Scripts that work on small files and fail on real ones
- Wrong output: bad parsing, wrong numbers, silent data loss
- Scripts that hang, leak memory, or run far too slowly
- Environment issues: dependencies, paths, encoding, venv
HOW I WORK
Send the code and a way to reproduce the problem: the failing input or a sample file, plus the exact error. I confirm I can reproduce it before you pay for anything. If I cannot fix it, I tell you and you do not order.
You get the fixed code, a short note on what was wrong and why, and a readme if anything changed in how you run it.
I do not touch code I do not understand, and I do not hand back a patch I cannot explain.

I take small, well-defined coding jobs: a script that does one thing properly, a bug that needs finding, code that used to work and stopped, a quick internal tool or integration.
Mostly Python. The first thing I ask for is a way to reproduce the problem - the failing input, a sample file, the exact error. Half the fix is usually in there, and I would rather hit the edge case now than after delivery.
You get readable code and a short readme, so you can re-run and change it yourself without coming back to me.
FAQ
What if you can't fix it?
Then you don't pay. I check that I can reproduce the problem before we start. If I get into it and can't solve it, I cancel the order and tell you what I found.
I can't share my whole codebase. Can you still help?
Usually yes. A minimal file that reproduces the error is enough for most bugs. If I do need more context, I will tell you exactly which part and why.
How fast is it?
Most single bugs come back within 24 to 48 hours. Tell me if it is urgent and I will say honestly whether I can hit your deadline before you order.
Do you work in other languages?
This gig is Python. Bash and SQL often show up alongside it and I handle those parts too. For anything else, ask first and I will tell you if it is outside what I do.
Will you explain the fix?
Always. You get what was wrong, why it happened, and what I changed. If the same class of bug can come back, I say where.
