You will get your SQL queries for maximum performance (Oracle, MySQL, PostgreSQL)
Project details
I optimize SQL queries focusing on real impact: shorter execution time, lower resource consumption, and greater system stability. I do not apply generic solutions; I analyze each case considering data volume, table structure, and usage pattern.
I have experience working with high-volume databases in critical environments, where a bad query directly affects the business. This allows me to quickly detect problems such as full table scans, inefficient joins, or incorrect use of indexes.
The result is not just a faster query, but a sustainable improvement in system performance. Ideal for systems that are already in production and need optimization without complex redesigns.

Delivery time starts when Esdrey receives requirements from you.
Esdrey works on your project following the steps below.
Revisions may occur after the delivery date.
Requirements reception
Client sends SQL queries, table structure, and problem context (current times, data volume).
Initial technical analysis
Evaluation of execution plan, detection of bottlenecks (joins, indexes, scans, subqueries).
