I will diagnose and fix your java spring boot API error
Andres R
About this gig
Your Spring Boot API is throwing errors. You've spent hours on Stack Overflow. Nothing works.
You don't need another "bug fixer." You need someone who understands WHY it's failing.
MY APPROACH
1. I read your logs and code not just the error message
2. I find the ROOT CAUSE, not the symptom
3. I fix it so it doesn't happen again
WHY ME
I've built production systems from scratch. My latest project: a veterinary clinic system (Spring Boot + PostgreSQL + JWT + Docker) with scheduling conflict detection, automated jobs, and PDF generation. I've faced the exact errors you're facing.
Not sure which? Message me first. Describe your error in 2-3 lines I'll tell you honestly which fits, or if you don't need me at all.
Let's fix this.

FAQ
Do I need to share my source code?
Not for the Diagnosis package. Logs and the failing endpoint are enough. For fix packages, I need access to the specific module — you can share only the relevant files, never your entire repo :)
What if you can't find the issue?
If I can't identify the root cause after a full diagnosis, I refund the Basic package in full. I don't charge for guesses.
Is my code and data safe with you?
Yes. I sign an NDA on request. All files are deleted after delivery. I never store client code or data on personal devices or share them with third parties.
