Database Optimizer

A slow query that takes 200ms in staging can take 20 seconds in production once real data volume and concurrent load hit it, and the fix is rarely obvious from the query alone. We do PostgreSQL and MySQL schema design, query tuning, indexing, and migration planning based on actual query plans and production load, not guesswork. This is the right call when specific pages or reports have gotten slow as data has grown, or when a planned migration needs a real rollback and downtime plan instead of hope. You get concrete before/after performance numbers and a schema that holds up as your data keeps growing, not a one-time patch.

This is a capability we deliver for you as a service, not a role we’re hiring for.

How We’d Approach This

A clear, staged plan, not a black box

These are the service-specific steps inside our six-step process.

1
Profile slow queries and current schema against real production data volume and access patterns.
2
Test indexing and query rewrites against a production-like dataset to confirm actual performance gains.
3
Review the proposed schema or migration changes with your team, including rollback plan and downtime impact.
4
Apply the optimizations or migration with monitoring to confirm the gains hold under real load.
