Get a focused fix for a reproducible Python bug, with a clear explanation and practical verification.

I reproduce the agreed issue, trace its cause, implement a targeted patch and run relevant checks. You receive the changed source files or a pull request, test results and concise setup notes.

Send the repository or relevant files, Python version, error output and steps to reproduce. We agree on scope and delivery before work starts. Small, isolated fixes can have a quick turnaround; broader debugging, dependency upgrades and ongoing maintenance are quoted separately.

This service covers one agreed issue. New features, extensive refactoring, deployment and unrelated bugs require a separate scope. No passwords or production secrets are needed in an initial inquiry.
