About this gig

I will investigate and fix a reproducible error in an existing local Python script. Please contact me before ordering so I can confirm that your issue fits the package.


Basic: one bug, up to 100 nonblank lines. Standard: up to two related bugs, up to 200 lines. Premium: up to two related bugs, up to 300 lines, plus one reusable regression test. All packages include 3-day delivery and one revision within the original scope.


Send the script, Python version, dependencies, error message, a small anonymized input and expected output. You receive corrected source code, a brief explanation and run instructions. I use AI-assisted tools where appropriate and personally review and test the delivery.


Not included: full applications, new features, cloud deployment, ongoing support, account access or production changes. Never send passwords, API keys or private customer records. Exams and assessments are excluded. Some issues depend on unavailable systems; feasibility must be confirmed first.
