About this gig

Your app was fast. Now pages take 10 seconds to load. I'll find out why.

I'm a backend developer working with MySQL on enterprise systems, where slow queries aren't an option. I diagnose performance problems at the root:

Slow query analysis with EXPLAIN plans and the index that actually fixes it

N+1 query problems from Hibernate/JPA and other ORMs

Locking & deadlock investigation (performance_schema analysis, not guesswork)

Schema and index design review

Query rewriting (bad JOINs, subqueries, IN() traps)

Connection pool and configuration tuning

What you get: measurable before/after numbers, not vague advice. Every recommendation comes with the reasoning, so your team understands the fix.

All work happens async via chat clear written reports you can share with your team.

Message me your slow query or symptoms first I'll confirm I can help before you spend anything.
