I will fix java spring boot bugs and rest API issues


About this gig
Have a reproducible Java or Spring Boot backend bug, failing REST endpoint, exception, or incorrect database behavior?
I will investigate the agreed issue, identify the cause, make a focused fix, and test the changed behavior. I keep the scope narrow so the code remains understandable and the delivery is predictable.
I can help with:
- Spring Boot startup and configuration errors
- REST API 4xx or 5xx responses
- Validation and exception-handling issues
- JPA, Hibernate, SQL, and transaction bugs
- Service and repository logic errors
- Dependency or test failures
- Performance issues with a clear reproduction case
Basic covers one small reproducible Java issue. Standard covers one defined Spring Boot backend or REST API bug. Premium covers a more complex issue with testing and fix documentation.
Please message me before ordering with the smallest reproducible project or relevant code, stack trace, expected behavior, actual behavior, Java version, Spring Boot version, and run instructions.
The $5 package is not for a full feature, full application, major upgrade, or broad refactor. Do not send passwords, production secrets, customer data, or private keys in chat.

FAQ
What do you need to reproduce the bug?
Relevant code or a minimal project, stack trace, expected and actual behavior, Java and Spring Boot versions, configuration sample, and run instructions.
What is included in the $5 package?
One small, clearly reproducible Java issue with a focused fix. New features, upgrades, broad refactors, and multiple unrelated bugs require another package.
