About me
I'm Kostya. Some of you might know me as Roark on X. I’m a senior product designer who works closely with crypto founders and DeFi teams. I love building things people genuinely want to try, and return to after that very first touch.

Constraints
There are things that quietly shape you as a person – I call them constraints. They sit deep in your mind and influence how you communicate, how you choose objectives, and how you make decisions. A framework behind every product you ship.
For me, the core constraint has always been curiosity. I’ve always been explorative by nature, drawn to understand how things work and why people behave the way they do. This evolved into a work style rooted in systematic thinking, responsibility, and experimentation. Think of it as a map, always gets me somewhere interesting.

What's now
For the past 3.5 years, I’ve been part of Brahma FI, designing and building a programmable account app at the intersection of DeFi and execution automation.
Right now, I’m exploring a few pet projects, jumping into hackathons with my friends, and writing a PhD thesis in philosophy – a mix that keeps both my analytical and creative sides alive.
