Over deze dienst
Java & Spring Boot Bug Fixing | Debugging | Error Resolution | 7+ Years Experience
Is your Java or Spring Boot application throwing exceptions, behaving unexpectedly, or not working as it should? I will investigate the root cause and deliver a clean, working fix.
What I can fix:
- NullPointerExceptions, runtime errors and stack traces
- Spring Security and JWT authentication issues
- Hibernate / JPA query and mapping errors
- REST API issues (wrong status codes, broken endpoints)
- PostgreSQL / MySQL connectivity and query problems
- Performance bottlenecks and slow response times
- Bean configuration and dependency injection errors
- Docker container and deployment issues
What you get:
- Fixed, working code with the bug resolved
- Clear explanation of what caused the issue and what was changed
- Post-delivery support for any related issues
How it works:
- Message me with a description of the issue and relevant code or error logs
- I confirm the scope and we agree on the package
- I deliver the fix within the agreed timeframe
Message me before ordering, a quick description of your issue is all I need.

Veelgestelde vragen
What information do you need to fix my bug?
A description of the issue, the relevant code or error logs, and your Spring Boot / Java version. A GitHub link or a zip of the relevant files works perfectly.
Can you fix bugs in an existing large codebase?
Yes. Share the relevant classes or modules — I don't need the entire project, just the code related to the issue.
What if the same bug reappears after delivery?
I provide free support for any issue directly related to the delivered fix. If the same bug comes back due to my fix, I will resolve it at no extra cost.
Do you fix bugs in plain Java projects (non-Spring)?
Yes. While I specialize in Spring Boot, I can debug plain Java applications, including issues with threading, collections, algorithms, and core Java libraries.
