I will fix java and spring boot bugs in your backend application
Ankita J
About this gig
Struggling with a stubborn Java bug? I'll find it and fix it.
I'm a full-time Java developer with deep experience in Spring Boot, REST APIs, JPA/Hibernate, and OOP design. I debug issues that are hard to track down, such as NPEs, Spring context errors, database mapping problems, incorrect API responses, and more.
What I fix:
· Java core exceptions (NPE, ClassCast, StackOverflow)
· Spring Boot bean/context/config issues
· REST endpoint errors and incorrect JSON responses
· JPA/Hibernate mapping & transaction problems
· Maven/Gradle dependency conflicts
What you provide:
· Your code (GitHub link or ZIP)
· Description of the bug and expected behavior
I'll return fixed code with a brief note on what was wrong and why. No unnecessary questions.

I'm a full-time Java developer specializing in Spring Boot REST APIs, JPA/Hibernate, and JUnit testing. I write clean, maintainable code and have hands-on experience with real production systems.
On Fiverr, I help clients fix tricky Java bugs, improve code quality through detailed reviews, and add solid test coverage with JUnit 5 and Mockito. I work quietly and efficiently — you'll get quality output without back-and-forth.
FAQ
Q: What information do you need from me to get started?
A: For bug fixing: share your code (GitHub link or ZIP) and describe the bug — what you expect to happen vs. what actually happens. For code review: share the code you want reviewed and any specific concerns. For JUnit tests: share the source c
Q: Can you work with my existing project structure?
A: Yes. I work with standard Maven and Gradle projects. As long as I can see the relevant code, I don't need to run your full application. For context-heavy bugs I may ask for the stack trace or logs — that's usually all I need beyond the code itse
Q: What if the bug turns out to be more complex than expected?
A: I'll let you know before I start if the issue appears out of scope. I won't charge more mid-order without your agreement. If the fix requires a higher package, I'll explain why and you can decide — no surprises.
Q: Do you offer revisions?
A: Yes — one revision is included on all packages. A revision means adjusting the delivered work based on the original requirements. Changes to the scope or new requirements are a separate order.
Q: Will you keep my code confidential?
A: Absolutely. Your code is used only to complete your order and is not shared or reused. If you need an NDA, message me before ordering, and I can sign one.
Q: Do you do calls or live debugging sessions?
A: No, I work asynchronously only — which keeps things efficient for both of us. You share the code and details, and I deliver the fix or review. If something is unclear, I'll ask via Fiverr chat (briefly and to the point).
