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.
