Is your web application freezing, facing high database CPU usage, or throwing query timeout errors?


I am an Oracle Certified Professional (MySQL 8.0 Database Developer) with 10+ years of backend and database engineering experience. I analyze execution plans and optimize indexes cleanly rather than applying temporary server restarts.


What I Can Optimize & Fix for You:

Slow Query Performance: EXPLAIN execution plan analysis, index tuning, and complex JOIN optimizations.

Deadlocks & Locking: Identifying transaction conflicts and blocking locks in InnoDB.

High Server CPU: Pinpointing resource-intensive queries and slow query log analysis.

Database Bloat & Maintenance: Table optimization, schema defragmentation, and safe storage cleanup.
