Engineer first, founder because it was faster.

I am Yasin Ergün — a software architect in Tallinn who has spent sixteen years building products for Europe, most of them with my own hands.

I started in PHP and Ruby on servers I kept alive myself, and never stopped caring about the part after launch. That habit turned into DevOps, then security, then the edge: today most of what I build is serverless and needs no servers at all.

The products came from problems I kept seeing. Travellers overpaying for data became Simtegre. Cafés paying monthly for a link page became Bentap. Sensors that phone home with everything became Estegre. Trackers without a product became Navibil.

BILPP OÜ is the company behind all of it, and where I take on client work: companies in Germany, the Nordics and Türkiye who want software built by someone who has run products, not just delivered them.
