Resume

13 years building products. The last few building the infrastructure that makes them.

About me

I'm a product designer who works at the boundary of design and engineering, building systems, tools, and workflows that scale design impact without scaling headcount.

I got here gradually. Early career: traditional product design across agencies, startups, and scaling SaaS teams. Mid-career: design systems became my primary medium. Recent work: AI-native infrastructure. A design system with a custom MCP server, an agentic prototyping workflow, a comprehensive accessibility audit. Things most designers don't build because they require operating in code.

I'm technically fluent. I ship React components, write Python, build MCP servers, and work directly in engineering codebases. I use Claude Code as my primary development environment. The quality of what gets built still depends on the decisions driving it. That part hasn't changed.

Education

M.S. & B.S., Avionic Systems Interface Design

2019
National Aviation University • Kyiv, Ukraine

The degree is unusual for a designer. Aviation interface design is a discipline built on safety-critical systems where ambiguity costs lives. Edge cases are not edge cases, they are the design. That framing has followed me into every product I've worked on since.

Beyond work

Working toward a private pilot's license. Drawn to the complexity of flight systems: navigation, weather, aerodynamics, and what they demand from interface design. Long-term goal: cross the Atlantic in a small plane.
