About this gig

Your Spring Boot app won't start and the clock is ticking.

Cryptic stack trace. A dependency conflict you've read 20 Stack Overflow threads about. Or AI-generated Java code that runs 90% of the way, then breaks. You've lost hours. It's still not fixed.


That's exactly what I do. I'm a professional Java developer building Spring Boot microservices every day not a generalist who "also does Java."

Send me your error. I'll tell you honestly if I can fix it before you pay a cent.

What you get:

  • Your bug found and fixed clean, working code
  • A plain explanation of why it broke, so it won't happen again
  • Clear comments, so you actually understand the fix
  • On Premium: a test that keeps it fixed for good


My promise: I work on it until it runs. No dumping code over the wall and disappearing.


Most bugs fixed within 24-48h. Fast, clear communication in English and German.

Stop fighting the error. Message me your stack trace now and let's get your app running today :)
