PostgreSQL & Database Performance Tuning

Most performance problems are database problems. I diagnose slow queries from execution plans, fix indexing and access patterns, and adjust schemas where needed, so your pages and APIs respond quickly under real load.

What I deliver

  • Query and execution plan analysis on slow pages, reports, and dashboards
  • Indexing strategy and removal of expensive scans
  • Schema and data-model adjustments for faster reads without breaking writes
  • Caching with Redis where it is the right tool
  • Before and after measurements so improvements are verifiable

When to hire me

  • Reports or dashboards take seconds to load and are getting slower as data grows.
  • Your API latency is inconsistent and the cause is not obvious.
  • You want an expert review of a PostgreSQL or MySQL schema before it becomes a problem.

Frequently asked questions

Which databases do you work with?

PostgreSQL mostly, plus MySQL, Redis, and NoSQL stores such as Firestore.

Do you need access to production data?

Not necessarily. Execution plans, schema, and anonymized or sample data are often enough to find the cause.

What results should I expect?

It depends on the cause. In production systems I have worked on, key API endpoints respond in under 200 to 300 milliseconds.
