04 — About

Engineer with one foot in science.

Hi, I’m Mykola, a fullstack developer from Kyiv. I’ve spent 3+ years building web and mobile products for international clients, and a big part of my recent work is in bioinformatics. That mix means I’m comfortable with messy data, unclear requirements and products where the interface has to make something complex feel simple.

I’m a Claude Certified Architect and use AI daily, both inside the products I build and to ship them faster.
