About this gig

tuck with a Java Spring Boot error? Let me fix it! Software bugs can halt your business or ruin your project deadlines. If your backend is throwing errors, crashing, or returning the wrong data, I am here to help.

As an experienced Java backend developer, I love diving into existing codebases, finding the root cause of the problem, and applying the perfect fix.

I can help you with:

  • Resolving compilation and runtime errors (NullPointerExceptions, BeanCreationExceptions, etc.)
  • Fixing REST API endpoint logic errors
  • Database connection issues (Hibernate, JPA, SQL)
  • Dependency conflicts (Maven)
  • Refactoring messy code for better performance

How it works:

  1. Show me the error logs and your code.
  2. I will identify the problem.
  3. I will deliver the fixed code with an explanation of what went wrong.

Message me with your error log before ordering for a quick assessment!
