I will fix bugs in your python, javascript, php or sql code fast
Argos
About this gig
The bugs that cost most don't crash. They quietly return a wrong number.
A worked example from my portfolio: a revenue report was short by £17,223.95
because pandas silently drops rows with a blank grouping key. 14 orders vanished
from every total, nothing errored, and it looked fine.
I debug Python, JavaScript/TypeScript, PHP, SQL and Bash. Most come back the same
day with the fix, and a test that fails on your old code and passes on the new,
so you can see it's gone, not take my word.
What you get:
- The actual fix, not a workaround
- An explanation of what was broken and why, so it doesn't come back
- A check for the same mistake elsewhere in the file
- Clean, commented code matching the style already in your project
What I need from you:
- The code (repo, zip, or pasted snippet)
- The exact error message or the wrong behaviour you're seeing
- How to reproduce it
Works with: Django, Flask, FastAPI, pandas/numpy, Node, Express, React, Vue,
Laravel, WordPress plugins, Selenium/Playwright, MySQL, PostgreSQL, SQLite.
Not sure if your bug fits? Message me with the error I'll tell you
honestly whether I can fix it and what it costs before you order.

I fix bugs and build small automation tools — Python, JavaScript, PHP and SQL.
Most of what I take on is whatever is blocking you right now: a bug you've lost a day to, a report whose numbers don't add up, a task you're still doing by hand every week.
How I work — I ask two or three questions before quoting, so the price and the date are fixed and there are no surprises later. I deliver early rather than late. You get working code, setup steps written in plain English, and an honest note on anything it doesn't handle.
If it's not something I can do well, I'll say so before you order.

FAQ
What if you can't fix it?
Full refund, no argument. And I'll tell you within a few hours if it's out of scope rather than sitting on it until the deadline.
Is my code confidential?
Yes. I don't reuse, publish or share client code.
Can you work directly in my repo?
Yes — add me as a collaborator. Or send a zip if you'd rather not give access.
What counts as one bug?
One reproducible failure. If fixing it reveals a second unrelated one, I'll tell you the price before doing anything — you'll never get a surprise charge.
