You will get SQL query optimization advice
Project details
Do you have an SQL query that is slow, timing out, or scanning too much data?
I have 17+ years of experience building and optimising scalable data systems, reporting platforms, and databases handling large volumes of data.
I will review your query and suggest practical ways to improve its performance. This may include query rewriting, index recommendations, execution plan review, table structure observations, or filtering/join improvements.
This is ideal for a focused review of one problematic query. If your issue involves many slow queries, high CPU, poor MySQL configuration, or wider database performance problems, please contact me first or check my MySQL database optimisation project.
