Fix Slow & Broken Spring Boot APIs | Java Backend Expert
100% Job Success

Lahore, Pakistan - 5:00 am local time
If your Spring Boot API is slow, failing, or returning incorrect data — I can fix it quickly and properly.

Most backend issues come from inefficient queries, poor service design, or scaling bottlenecks. I specialize in identifying and fixing these problems in production systems.

I’m a Java backend engineer with 5+ years of experience working on real-world systems across SaaS, logistics, and data-heavy applications.

What I help clients with:

Fixing slow or crashing Spring Boot APIs
Debugging incorrect data, joins, and aggregation issues
Optimizing SQL queries (MySQL, PostgreSQL)
Refactoring messy or hard-to-maintain backend code
Designing scalable microservices and REST APIs

Recent Work:

Reduced API response time from 2.5s → 200ms
Fixed data mismatch in reporting caused by incorrect joins
Stabilized backend handling high request loads

I don’t overpromise — I diagnose the problem fast, communicate clearly, and deliver clean, reliable solutions.

If you’re dealing with a backend issue and need it fixed without wasting time — let’s talk.
