About Shayan
Fix Slow & Broken Spring Boot APIs | Java Backend Expert
100%
Job Success
Lahore, Pakistan - 9:24 pm local time
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.
