You will get Design or optimize your PostgreSQL or Oracle database
Project details
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 (EXPLAIN plan review)
- Index tuning and SQL 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 gains. Message me before ordering
with your schema or slow query so I can scope the work.
