Sobre este Serviço

A slow query costs you every single day - in server bills, in user patience, in reports nobody waits for anymore. I write and fix SQL for a living.


I am a MySQL developer who has designed and optimized databases behind real business applications. Whether you need a complex query written from scratch or an existing one made fast, I start by understanding your data structure - not by guessing.


What I deliver:

  • Complex SELECT queries: multi-table JOINs, subqueries, aggregations
  • - Optimization of slow queries: EXPLAIN analysis, indexes, rewrites
  • - Stored procedures, views, triggers and functions
  • - Report queries: turn "I need a report showing..." into working SQL
  • - Clear explanation of what I changed and why

How it works: send me your table structures (CREATE statements or a plain description) and what you need. I will confirm scope before you order if anything is unclear.


Primary: MySQL and MariaDB. Also comfortable with PostgreSQL and SQLite.


Slow query emergencies welcome - the Basic package is a fast fix for one query with a before and after timing report.
