You will get Python backend bug fixing and API troubleshooting support


Project details
You will get focused Python backend bug fixing and API troubleshooting support for your existing backend, endpoint, database workflow, integration, or runtime issue.
I help investigate the problem, understand the expected behavior, review the relevant code, identify the likely root cause, and apply a focused fix when possible. This service is a good fit for FastAPI, Django, Flask, SQLAlchemy, REST APIs, validation issues, database errors, external API problems, deployment/runtime errors, and backend workflows that are not behaving as expected.
My goal is not to rewrite your whole codebase. I focus on the specific issue, explain what was wrong, fix the affected area within the agreed scope, and provide concise notes so you understand what changed and what may need attention next.
Note: for this backend service, Upwork’s “number of pages” field refers to backend units such as issues, endpoints, workflows, or troubleshooting areas, not visual website pages.
