I will fix python or fastapi bugs with tests and clear documentation
Xiangb
About this gig
Fix a reproducible Python or FastAPI bug with a focused patch, tests and clear run notes. Please contact me before ordering so we can check reproducibility and agree on scope and an acceptance test.
Basic: one pre-screened code/config issue in a minimal project. Includes diagnosis, patch, regression check of the agreed test and run instructions.
Standard: one endpoint or business path, up to two directly related issues, with usable mock APIs/data. Includes tests and environment notes.
Premium: only after code review, one bounded cross-component issue with a fully runnable test setup. Includes an integration test and handover.
Revisions correct the agreed brief; new features or unrelated bugs require separate agreement. No production SSH/cloud administration, real sensitive data, payments/security changes, migrations or ongoing support.
I use AI-assisted tools to customize the work to your supplied code. Delivery includes test commands, recorded results and any limits. A synthetic test example is available; it is not a client project. Feasibility depends on the supplied reproduction; not every bug can be fixed within a package.

FAQ
What do you need from me to start?
Send sanitized minimal code, dependency/lock files, run command, error, reproduction steps, fake sample data and expected result. Confirm you have rights to share it. Remove secrets and personal data. Contact me before ordering so we can agree on scope and a test.
Can you work with private repositories?
Prefer a sanitized minimal project or mock setup. Share only code you are authorized to disclose. Never send passwords, API keys, production access, customer records or other sensitive data. Production SSH/cloud administration is outside this gig.
What if the issue is larger than the selected package?
Please contact me before ordering to check feasibility. Packages cover only the agreed reproducible issue. If scope changes or the setup cannot reproduce it, we will discuss next steps through Fiverr before additional work. No automatic upgrade or guarantee that every bug is fixable.
What do revisions and delivery include?
Revisions correct the agreed brief and acceptance test; they do not add new features or unrelated fixes. Delivery includes the patch, test commands/results, run notes and known limits. Standard adds environment notes; Premium adds an integration test and handover for the reviewed scope.
