About this gig

Is a bug blocking your release or breaking your production app? I'll find it, fix it, and explain what went wrong so it doesn't happen again.


With 5+ years of Java and Spring Boot development, I've debugged everything from complex NullPointerExceptions and Spring Security misconfigurations to React state issues and database query bottlenecks.


What I fix:

- Spring Boot errors (startup failures, bean issues, config errors)

- REST API bugs (wrong responses, auth failures, 500 errors)

- Spring Security / JWT authentication problems

- Hibernate / JPA query and mapping issues

- React bugs (state management, API integration, rendering)

- MySQL / Oracle database errors


What you get:

- A fully fixed, working codebase

- Clear explanation of the root cause

- Prevention tips so it doesn't happen again

- Clean, readable code changes


I work with GitHub, GitLab, ZIP uploads, or screen sharing.


Message me with your error before ordering I'll confirm I can fix it within 1 hour.
