About this gig

Is your Spring Boot app throwing errors, failing to start, or returning wrong data? I'll find the cause and fix it fast.


I'm a Senior Software Engineer with 5+ years building production Java Spring Boot microservices, REST APIs and secure login systems for real companies.


What I can fix:

  1. Startup errors, dependency and build problems (Maven, Gradle)
  2. REST API bugs and wrong responses
  3. Database issues with JPA, Hibernate, MySQL or PostgreSQL
  4. Spring Security, OAuth2 and Keycloak login problems
  5. Java version upgrades, such as Java 11 to 17
  6. Docker and deployment errors


How it works:

  1. Message me with the error and a short description
  2. I confirm the fix and delivery time
  3. I fix it, test it and explain what was wrong


You get working code, a short explanation of the fix, and support if something is not right.


Please message me before ordering so I can check your issue first.
