I will debug and fix bugs in python scripts and fastapi apps
Andrea R
Informazioni su questo servizio
Is your Python script crashing, returning the wrong result or failing after a change?
I will investigate and fix one reproducible issue within the selected package.
I work with:
- Standalone Python scripts.
- FastAPI and Flask endpoints.
- Python workflows using SQL or documented REST APIs.
You receive the corrected source code or patch, an explanation of the cause and steps to verify the fix. Standard includes a focused regression test; Premium includes a regression test or reproducible integration check.
Basic covers one standalone script issue without external services.
Standard covers one endpoint issue.
Premium covers one workflow failure involving a database OR external API.
AI-generated code is welcome if you can provide the source and run instructions.
New features, full rewrites, frontend fixes and production deployment are outside these packages.
I'm Andrea, a backend developer with experience in insurance and industrial automation.
Send the traceback, relevant code, reproduction steps and expected behaviour before ordering. If a separate diagnosis is needed, we will agree on it first.

FAQ
Which package should I choose?
Basic covers one standalone script without frameworks, APIs or databases. Standard covers one FastAPI/Flask route or its validation/response logic. Premium covers one failure involving one SQL database OR one documented REST API. Send a reproducible example first.
What do you need to reproduce the issue?
The source or smallest failing example, full traceback, dependencies, Python version, sample input, expected output and exact run steps. For integrated issues, provide documentation and a test environment with the necessary access.
Can you fix code generated by an AI tool?
Yes, provided you have the source code, dependencies and run instructions. I assess the Python issue and its surrounding dependencies. This does not include rebuilding an entire app, redesigning it or fixing unrelated frontend problems
Does one error message always mean one small bug?
No. One symptom can have several causes. I assess the reproduction and scope first. The packages cover one agreed failure in the stated environment, not any number of hidden problems or a complete application audit.
What if the cause is not clear?
If the issue needs extended investigation, I can offer a separate paid diagnosis with explicit deliverables before a fix order is agreed. A diagnostic report is not substituted for a correction already promised.
Will you change my production application?
The packages cover a code patch and verification in an agreed local or test environment. Live deployment, production database changes, infrastructure work and ongoing monitoring are separate and require an agreed plan.
Do you fix FastAPI authentication or database issues?
An isolated issue may fit after assessment. An existing SQL query or integration failure can fit Premium. New login systems, permissions redesign, data migrations, security audits and broad performance work need a custom quote.
What does a revision include?
A revision addresses the same agreed failure and acceptance criteria. Another bug, feature or environment is new work. If my delivered patch does not meet the agreed requirements, I will address it.
Can you guarantee any Python app can be repaired?
No. I assess feasibility and access before agreeing to a fix. Some projects require unavailable services, larger changes or specialist knowledge. If that applies, I will explain it rather than promise a universal fix.
