About this gig

Having an issue with your Java Spring Boot application? I can help you quickly identify and fix bugs, errors, and small feature issues.

I have 9+ years of experience working with Java, Spring Boot, REST APIs, microservices, databases, and enterprise applications.

What I can help with:

  • Fix Spring Boot bugs and runtime errors
  • Debug REST APIs and backend issues
  • Fix database and JPA/Hibernate problems
  • Add small features or API endpoints
  • Fix Spring Security, JWT, and authentication issues
  • Integrate third-party APIs
  • Improve and troubleshoot existing backend code
  • Add unit tests for fixes and features

Why work with me?

  • Clean and maintainable Java code
  • Proper root-cause analysis instead of temporary fixes
  • Clear communication
  • Practical solutions focused on your existing application

Please contact me before ordering if your issue is complex or requires major changes. I will review the requirements and confirm the scope first.
