I will write and optimize sql queries for your database
About this Gig
I write, fix, and optimize SQL queries for your database whether you need a complex report, a slow query sped up, or a database schema designed from scratch. I work with MySQL, PostgreSQL, and other SQL databases, and I can help with:
- Writing SELECT, JOIN, and subquery-based queries for reports or data extraction
- Optimizing slow queries and adding proper indexing
- Designing normalized database schemas (tables, relationships, keys)
- Fixing bugs in existing SQL code
- Writing stored procedures, views, and triggers
Send me your requirements or existing database structure, and I'll deliver clean, well-commented, working SQL. Revisions included until you're satisfied.

FAQ
What database systems do you work with?
MySQL, PostgreSQL, and SQL Server. Let me know your system and I'll confirm compatibility.
Can you optimize an existing slow query?
Yes — send me the query and table structure, and I'll identify bottlenecks and rewrite it for performance.
Do you need database access?
Not always — for query writing I just need your table structure (schema). For live optimization work, we can discuss secure access options.
