I will fix your spring boot and spring security bugs and errors

Stuck on a Spring Boot error you have already spent hours on?

Send me the stack trace and I'll tell you if I can fix it - before you order.

I'm a backend engineer working with Java and Spring Boot every day. I debug and fix:

• Spring Security: 401/403, CORS, filter chain, OAuth2 and JWT issues
• Startup failures: bean creation, circular dependency, autowiring
• JPA / Hibernate: lazy loading, N+1, mapping and transaction errors
• REST layer: serialization, validation, exception handling
• Build and config: Maven/Gradle, profiles, application.yml, Docker

HOW IT WORKS

1. You send me the error + repo or a zip
2. I tell you the right package and a real delivery time - free
3. I fix it, explain the root cause, and hand you a clean commit

Works on Spring Boot 2.x and 3.x, Java 8-21.

You get the fix, the reason it happened, and how to avoid it next time. I don't close the order until it runs on your machine.

Message me first with your error - I usually reply within a couple of hours.
