Get one clearly scoped Python or FastAPI bug fixed, with a regression test and practical handover notes.

For $125, I will investigate and repair one reproducible defect in one small Python module or up to two existing FastAPI endpoints. Deliverables: a focused code patch, a regression test covering the agreed failing case, and instructions to run and verify the fix. One revision addressing the agreed acceptance criteria is included.

Please message me before ordering with the expected and actual behavior, dependency versions, and a runnable example using synthetic or redacted data. We will confirm feasibility and acceptance criteria first. Delivery is within three business days after scope is agreed and the required materials are available.

New features, major refactors, production deployment and security testing require a different scope. I work from a development copy; please do not send passwords or production customer data.

I use AI assistance where the project permits it, and review and test the resulting changes. If your project restricts AI use, please tell me before we agree the work.
