You will get designed PostgreSQL database or fix your slow SQL queries


Project details
Slow queries killing your app performance? Need a database designed properly from day one? I work with PostgreSQL and SQL Server across production applications and can help with both.
Schema Design: I design normalized, well-indexed database structures built for real traffic. Proper relationships, correct data types, and indexes planned from the start rather than added as a fix later.
Query Optimization: I run execution plans on your slow queries, find missing indexes, rewrite inefficient joins, and explain exactly what was wrong and what I changed.
What I work with:
PostgreSQL
SQL Server
SQLite
What you receive:
Clean schema or optimized queries
Written documentation of all decisions made
Clear explanation of what was wrong and why the fix works
Not sure which package fits your situation? Message me first and I will point you in the right direction.
