the bottleneck for many sites

Database
optimization.

I speed up database performance: find slow queries, add missing indexes, fix structure issues, and eliminate bottlenecks under real-world load. I work with MySQL and PostgreSQL.

on heavy queries.

When a site 'slows under load', the cause is often not the code but the database: queries without indexes, suboptimal structure, and operations scanning millions of rows. I analyze execution plans and eliminate these bottlenecks in priority order by impact.

01 / What's Included

What's included in database optimization

Slow queries

I find the heaviest queries via slow log and profiling, then analyze their execution plans.

Indexes

I add missing indexes and remove useless ones — speeding up reads without slowing writes.

Data structure

I fix problematic schemas, data types, and relationships that prevent the database from performing well.

Load handling

I optimize for real traffic patterns, eliminating locks and concurrency bottlenecks.

FAQ

Частые вопросы

Which databases do you work with?
Primarily MySQL / MariaDB and PostgreSQL. The approach is the same: query plan analysis, indexes, and structure — specific techniques adapted to your DBMS.
