I will debug and fix your java spring boot backend issues


About this gig
Production bug eating your afternoon? I'll find it and fix it.
I'm a backend engineer with 13+ years of experience building and maintaining Java & Spring Boot applications. I specialize in production issues that aren't solved by a quick Stack Overflow search or not a GPT-friendly bug.
I can help with:
- Spring Boot errors and unexpected behavior
- Hibernate/JPA issues (N+1, lazy loading, mapping problems)
- REST API bugs, validation, and endpoint issues
- Performance problems (slow APIs, memory leaks, connection pools)
- Dependency conflicts and Java 817/21 upgrades
- Inherited code-bases with little or no documentation
How it works:
- Send the bug details (error, expected vs. actual behavior, and reproduction steps if available)
- I'll confirm the scope and timeline before you order
- You'll receive the fix plus a clear explanation of the root cause and how to prevent it
Why work with me?
I have 13+ years of production backend experience. I focus on finding the real cause, not temporary work-aroundsand include a concise root-cause summary with every fix.
Not sure which package you need? Send me the details, and I'll recommend the right option.

FAQ
Do you need access to my full codebase, or just the buggy part?
Usually just the relevant module/repo, or a minimal reproduction if you can share one. Yet it depends on a type of bug.
What if the bug turns out to be bigger than expected once you look at it?
I'll tell you before doing extra work. If it's outside the package scope, I'll send a fair custom offer for the difference — no surprise charges.
Can you work with AWS / Docker / Kubernetes deployments too?
Yes- in most of the cases, if the bug is in the deployment config or environment rather than the application code itself, let me know in your message and I'll confirm I can help before you order.
Do you sign NDAs?
Yes, happy to sign a reasonable NDA before you share code, especially for proprietary/production systems.
What do you need from me to get started?
A clear description of the bug, any error logs/stack traces, and repo/code access (or a minimal reproduction). The clearer the repro, the faster the fix.
