Sheet 04 · About
I build the parts of a product people touch.
I'm a senior front-end engineer in Kyiv. I work with distributed product and design teams on React and Next.js applications, most often at the layer where a team turns design decisions into components and data contracts.
Since 2021 I've built sports video products. I started on Rapid Replay at Launch Labs, and after NBC Sports Next acquired it, I moved to SportsEngine Play, where I own the front end across the web app, the admin platform and the mobile app.
I like small typed contracts, screens that lead with the important thing, and motion that tells you what changed. You can see some of that on this site: click anywhere, or press T.

02Working notes
- Note 1
Contracts before components
I'd rather ship a component with three typed variants than one with twelve boolean props. The next engineer can read a union type in a few seconds.
- Note 2
Answer the main question first
A screen should answer the user's main question before it offers detail. I cut or defer anything that competes with that answer.
- Note 3
Check it in a browser
A green build proves the code compiles. I also open the page on a phone, tab through it with a keyboard, and read the console before I call it done.
