About this gig

BUG IN. FIX OUT. USUALLY WITHIN 24 HOURS.


Stuck on a bug? Send your code or error trace. I find the root cause, fix it, and explain what happened in plain language. Every order includes the full treatment:


What you get:

  • Root-cause investigation, not guesswork
  • Working fix with fix documentation
  • Detailed code comments
  • Up to 3 revisions until it's right
  • Delivery in 24 hours, usually much faster


Works with: Python, Node.js, scripts, small apps, data pipelines.


Why $5? New seller, building a review base. The price is introductory, the work is not. Every fix ships with documentation most sellers charge extra for.


Honest limits: one root cause per order, and I fix its full chain: if the bug you spot leads to two more, I chase the chain through. Independent bugs in different features need separate orders or a custom quote. If I can't fix it, I say so and you don't pay.
