I work with SQL scripts, .sql files, ERD diagrams (PDF/PNG), and can import sample data in CSV, Excel, or direct database snapshots (MySQL, PostgreSQL, SQL Server).

You’ll get one custom SQL query plus a mini-ERD sketch in 3 hours—so you can see my database design approach risk-free.

Basic covers up to 3 tables, Standard up to 5, Premium up to 10. Each includes ER diagrams, normalization, and relationship mapping.
Can you optimize existing queries?
Yes, I analyze, refactor, and tune your SQL queries for performance, adding indexes or rewriting joins to speed up results.
