About

Hey, I'm Kostya, a designer from Kyiv, Ukraine. For 10 years I've been building things on the internet, involved in every aspect of creating a product: marketing, business, growth, development, and finally design.

I've spent the last six years designing for crypto and fintech — trading and transaction UX for general-purpose infrastructure, on both onchain and centralized sides. I've been a crypto user myself since 2019.

Wherever I land, I set up constant lines of communication with the dev, product, and business teams to stay aligned on what we're shipping and where we're headed. All of that has given me the chance to work alongside great projects and talented people — and each new experience has raised the bar for how I think about and build tech products.

For the past 4 years I've worked at Brahma FI, designing a programmable account app that combines DeFi with execution automation. Brahma was recently acquired by Polymarket.

Currently I'm building a few personal projects, jumping into hackathons with friends, and writing a PhD thesis in philosophy — a mix that keeps both my analytical and creative sides alive.
