I will fix spring boot, java, and rest API bugs fast
Swarna
About this gig
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.
