Sobre este Serviço

Your Spring Boot backend is broken and you need it fixed not explained, fixed.


I'm a Java backend developer who builds and runs a live production system 

(Spring Boot + MySQL + React, deployed on a Linux VPS with nginx). I've 

personally debugged and resolved real production issues: blocked SMTP ports 

breaking order emails, broken authentication flows, server crash recovery, 

and more. I don't just patch code I find the actual root cause.


What I fix:

REST API errors (500s, 404s, broken endpoints)

Spring Boot startup/config failures

Authentication & JWT issues

Database connection & query errors (MySQL)

Null pointer exceptions, dependency conflicts, build failures

Deployment & server-level issues (nginx, systemd, VPS)


Why work with me:

I run my own live Java backend in production I know what "broken in 

 prod" actually means

Clear communication, no jargon-dumping

Fixes explained, not just delivered


Send me your error message or a GitHub link and I'll tell you honestly 

if I can fix it before you order.
