I will fix bugs and errors in your java spring boot application
Rahamathullah
About this gig
Is your Java or Spring Boot app throwing exceptions, returning wrong data, or failing to build? I'll find the root cause and fix it fast.
What I can fix:
- NullPointerExceptions, 500 errors and unhandled exceptions
- - REST API endpoints returning wrong or empty responses
- - Spring Boot startup / bean / dependency injection errors
- - Database / JPA / Hibernate query and mapping issues
- - Maven / Gradle build and dependency conflicts
- - Broken logic in controllers, services or repositories
How it works:
- You share the code (GitHub repo or zip) and describe the bug
- 2. I reproduce it, find the root cause and fix it
- 3. You get working code plus a short explanation of what was wrong
I'm a Java backend developer working daily with Spring Boot, REST APIs and databases. Clean, tested fixes and clear communication. Message me before ordering so I can confirm scope.

Backend-focused Java developer specializing in scalable, secure REST APIs and microservices with Java 17, Spring Boot, Spring Security, JPA/Hibernate and PostgreSQL. I build clean, maintainable service architectures and tune database performance, recently cutting API latency by around 65 percent through query optimization. I have shipped production features for a multi-module food-ordering platform, including role-based access and JUnit-tested logic. Need a new backend, a REST API integrated, or a Spring Boot app improved? I deliver reliable, well-documented code on time.
