I will fix bugs and errors in your java spring boot and react application
Ibtissam Rh
About this gig
Is your Spring Boot or React app throwing errors you can't fix?
I'm a fullstack Java developer. I find the real cause and fix it - no guessing, no band-aids.
WHAT I FIX
- Spring Boot: 500 errors, NullPointerException, bean & dependency injection, JPA/Hibernate mapping, lazy loading, N+1 queries
- Security: Spring Security, JWT, login/auth, CORS
- Database: SQL errors, MySQL/PostgreSQL connection, migrations
- React: broken state, useEffect loops, re-renders, props, routing, hooks
- API: frontend not receiving data, 401/403/404, failed fetch or axios calls
- Build & run: Maven/Gradle errors, app won't start, deployment issues
WHY ME
- Root-cause fix, not a workaround
- Clear explanation of what was wrong, so it doesn't come back
- Clean code that matches your existing style
- Fast replies and revisions until it works
HOW IT WORKS
1. You send your code (GitHub or ZIP) + the error message
2. I reproduce and diagnose
3. I deliver the fix + a short explanation
Not sure which package? Message me first - I'll look at your issue for free and tell you exactly what you need.

FAQ
How do I know you can fix my bug before I order?
Message me first with the error message and a screenshot. I'll review it for free and tell you honestly if I can fix it, which package you need, and how long it will take. If I can't fix it, I'll tell you straight away.
What counts as one bug?
One specific issue with one root cause — for example "login returns 401" or "the table doesn't render". If fixing it reveals a second unrelated issue, I'll tell you before doing any extra work.
Is my code safe and private?
Yes. Your code stays confidential and is never reused or shared. I'm happy to work in a private repo, and I can sign an NDA on request.
What if the fix doesn't work?
I keep working until the issue is actually resolved — revisions are unlimited. I don't mark an order complete on a fix that only half works.
What do you need from me to start?
Your project, the exact error message or stack trace, steps to reproduce it, and what you expected to happen. The more detail, the faster the fix.
