Backend Debugging & Bug Fixing
Nikita Savchuk
I will debug and fix backend issues in your Python or FastAPI application.
If your backend has errors, broken endpoints, unexpected API behavior, database problems, or unstable logic, I can help identify the cause and fix it.
What I can help with:
debugging FastAPI applications
fixing broken API endpoints
request/response and validation issues
business logic bugs
async/await and dependency issues
database query and integration problems
error handling improvements
logging improvements
testing affected functionality after fixes
You’ll get:
bug investigation and root-cause review
fixed and improved backend code
clear communication about what was wrong
stable changes without unnecessary rewrites
This service is focused on practical fixes, clear code, and getting your backend working properly again.
FAQs
Can you work on an existing codebase without rebuilding it?
What if there are multiple issues?
Do you test the fixes too?
