About this Gig
Slow queries? Messy tables? Need a database built right the first time? Im Umar, a Microsoft Certified Data Engineer (DP-600, DP-700) with 3+ years of experience in SQL Server and PostgreSQL.
What I do
- Design relational databases with a clear ERD and proper normalization
- Write and fix SQL queries (joins, subqueries, CTEs, window functions)
- Speed up slow queries with indexing and query rewrites
- Build stored procedures, triggers and functions
- Set up tables, permissions and data import/export
How it works
- You send your requirements or the slow query
- I confirm scope and timeline before starting
- I deliver the schema, ERD or optimized queries, tested
- You get clear notes so you can maintain it yourself
Good fit for: startups, app developers, analysts and small businesses.
