About this gig
Is a Java or Spring Boot bug blocking your application?
I am a software architect with 13+ years of professional experience building and supporting enterprise backend systems. I will investigate your issue, identify the root cause, and provide a clean, maintainable fix.
I can help with:
- Spring Boot startup and configuration errors
- REST API bugs and incorrect responses
- Spring Security, JWT, and authentication issues
- JPA, Hibernate, SQL, and database problems
- Maven or Gradle build failures
- Microservice communication and Kafka issues
- Performance, logging, and exception handling
- Docker and deployment configuration errors
You will receive the corrected source code, a short explanation of the fix, and testing within the agreed scope.
Please message me before ordering with the error, logs, expected behavior, and relevant code. Credentials and private data should never be included.

FAQ
What counts as one bug?
One reproducible issue with one expected outcome. Related failures may require a larger package.
Can you work on an existing codebase?
Yes, provided the relevant code, setup instructions, and safe access are available.
Do you guarantee every issue can be fixed?
I review the evidence before accepting. If the cause depends on unavailable systems or credentials, I will explain that before the order.
