About this Gig

Slow queries or messy schema? I design clean relational databases and make

slow ones fast.


 I provide:

 - Database schema design (tables, relationships, constraints, indexes)

 - Slow query analysis and optimization

 - Index tuning and EXPLAIN plan review

 - SQL writing and refactoring (joins, aggregates, stored procedures)

 - JPA/Hibernate mapping and performance fixes (N+1 query removal)

 - Data modeling for new applications


 Works with PostgreSQL, Oracle, and MySQL. You get clean SQL, clear

 explanations, and measurable performance improvements.


 Message me before ordering with your schema or slow query so I can scope the

 work.
