FastAPI Backend Debugging & Bug Fixing -- 2

FastAPI Backend Debugging & Bug Fixing

I need an experienced Python/FastAPI developer to debug and fix issues in an existing backend application.

Tasks:

Review the existing FastAPI backend and identify the root causes of reported issues
Debug API endpoints, request/response handling, validation, authentication, and business logic
Fix errors, exceptions, and unexpected API behavior
Check database interactions and API integrations where relevant
Review async/await and dependency handling for potential issues
Improve error handling and logging where needed
Test the affected endpoints after making fixes
Make sure existing functionality is not broken by the changes

Requirements:

Strong Python and FastAPI experience
Experience debugging REST APIs
Familiarity with PostgreSQL or similar databases
Ability to work with existing code rather than rebuilding the application
Clean, maintainable code and clear communication

I will provide the existing source code, bug details, and access to the necessary development environment. Please explain your relevant FastAPI debugging experience and your estimated time/cost for the work.
