About this gig

Are you struggling with a Java or Spring Boot error that is stopping your project from working?


I will investigate, debug, and fix Java code based on the agreed requirements.


I can help with:


  • Java compilation and runtime errors
  • NullPointerException and other exceptions
  • Spring Boot application errors
  • REST API and JSON response issues
  • Maven dependency and build problems
  • Gradle configuration errors
  • Spring Data JPA and database issues
  • Controller, service, and repository bugs
  • Logic errors and failed JUnit tests
  • Code cleanup and basic performance issues


You will receive:


  • The corrected source code
  • A clear explanation of the problem
  • Details of the changes made
  • Basic testing of the repaired functionality
  • Suggestions to help prevent the issue from happening again


Please contact me before ordering if your project has multiple unrelated bugs, requires a private server or database, contains a large legacy codebase, or cannot be run locally.


Each package covers the stated number and complexity of bugs. New features, major redesigns, or additional unrelated issues require a Gig Extra or custom offer.
