Full-Stack Developer
Hi, I'm Andrii. I build beautiful software that performs as well as it looks.
I’m a full-stack engineer with 2 years building platforms, startup products, and scalable web applications — from first commit to production at scale.
(01) About
A design-minded developer obsessed with performance, clean architecture and user experience.
For the past two years I’ve helped startups and product teams turn ambitious ideas into software people genuinely like to use. I care about the whole stack — the database query, the API contract, the animation curve.
My work sits at the intersection of engineering and design: fast, accessible, and quietly considered. No fireworks, just products that feel right.
