Yasin Ergün · Tallinn, Estonia
I build software that ships.
Founder, architect, full-stack engineer. Sixteen years of products for Europe — from eSIM apps to edge AI — usually as the person who writes the code.
In one breath
Most software dies between the deck and the deploy. I sit in that gap: I design the system, write most of it, put it on the edge, and stay until it earns. One person, the whole stack, no hand-offs.

01 Selected work
Things I built and still run.
Own products first — they are the honest portfolio. Then the studio, where the same stack ships for clients.
02 Capabilities
The whole stack, one pair of hands.
No hand-offs between design, backend, mobile and ops — the person who scoped it ships it.

04 How a project runs
Small team. Short loop.
- 01
A call, then a page
Thirty minutes to understand the problem; a one-page plan with scope, stack and price within two days.
- 02
Weekly shipping
Something usable every week, on a real URL. You see progress, not status reports.
- 03
Launch and stay
Deploy on your infrastructure or mine, monitoring included. I stay for the first months — that is when products are decided.
