Serhii Ocheretenko — a full-stack developer who takes products from zero to one: backend, frontend, databases, and the infrastructure that ships them.

Serhii OcheretenkoFull-stack developer · Kyiv

I started out teaching math and physics, then followed the part I liked most — building the systems behind the classroom — into engineering full time. Today I work full-stack and lead the martech function at SKELAR.

Most of my work is zero-to-one: standing up whole products end to end — backend and frontend, payment infrastructure, internal tooling, and the marketing funnels around them — built to hold up under millions of users. I care about pragmatic architecture and systems a small team can actually reason about.

I've led teams more than once — math and physics teachers at Unext, an engineering team at CML, and now back-office strategy at SKELAR — usually by being the person willing to own the whole problem.
