About this gig

Are you stuck with a backend issue and need a fast, clean fix without rebuilding the whole system?
I will debug and fix bugs in your Java Spring Boot backend so your API works reliably again.

Debug Spring Boot controllers, services, and repositories
Fix authentication or authorization issues (JWT / Spring Security)
Resolve configuration problems (application.yml / application.properties)
Fix dependency or startup errors
Update API logic or implement small backend improvements
How I work

- I explain what was wrong and how it was fixed (if needed)
