About this Gig
Slow queries eating into your app's performance? I turn slow, bloated SQL into fast, production-ready code often cutting execution time by 10x or more.
Database developer since 2016 (10+ years), working across MS SQL Server, MySQL, Oracle, PostgreSQL, Teradata, Databricks, and Access for multinational companies and individual freelancers worldwide.
What I do:
- Query optimization (indexing, execution plan analysis, rewrites)
- Stored procedures, functions, triggers, views
- Database design, ERDs, and relational modeling
- Database normalization and administration
- Import/export, backups, bug fixes
- ETL pipelines on AWS and Azure
Send me your slow query or current schema and I'll tell you exactly what's wrong before you order no guessing, no wasted spend.

FAQ
What information do you need to get started?
Send me your slow query, database schema, or connection details (read-only access is fine) and a short description of the issue. I'll review it and confirm scope before we start.
Which databases do you work with?
MS SQL Server, MySQL, PostgreSQL, Oracle, and Teradata. If you're unsure which applies to you, just message me and I'll confirm before you order.
How fast can you deliver?
Most single-query optimizations are delivered within 24 hours. Larger audits or multi-procedure work take 2-5 days depending on scope, which we'll agree on upfront.
