About this gig

Tired of unexpected bugs crashing your Spring Boot app? I've got your back.


I'm a professional Java backend developer with solid experience maintaining and debugging Java Spring Boot systems in real-world production. Whether it's a null pointer, failed dependency injection, or that annoying 500 error I'll trace, debug, and squash it.


What I offer:

  • Fix runtime or compile-time errors
  • Debug backend API issues (REST)
  • Resolve application crashes
  • Dependency conflicts (Maven/Gradle)
  • Database connection/configuration errors
  • Spring Security or OAuth issues
  • Meaningful explanation of what went wrong and why


Why me?


Real-world experience in enterprise-grade systems

Clean, safe, and maintainable fix no hacky shortcuts

Clear communication & delivery with log analysis if needed


Lets bring your system back on track. Drop me a message before ordering!
