Contact & Consulting

A database and Postgres specialist.

I’ve put in my 20K+ hours with many Postgres-heavy businesses in Europe, like Zalando, BMW, Klarna, Cognite - and thus have developed a pretty good gut feeling of what works reasonably well for some purpose and what not.

Occasional speaker at conferences, co-founder of Estonian Postgres User Group. An interview with me on postgresql.life from some years ago.
