Selected work

Products I've designed and shipped over 6+ years, from apps used by millions at 4PLAY to our own games at TAO STUDIO. I design them, and most of the time I build them too.

    4PLAY · Product design & build

    Formerly KimGBister, GiftBank and 1GB

    One product I've designed through every rebrand. It started as a viral social quiz and grew past one million users. I also built its WebView mini-games (Simon Says, Stack Tower, Flappy Bird) on the Game Hub API with a FreeByte token economy, and moved kazan-kazan.com from Framer to Next.js, Supabase and Cloudflare.

    How I work

    • Design and code, one person

      I take products from Figma to production myself with SwiftUI, React and Next.js, so nothing gets lost in handoff.

    • Behavior-led

      Gamification, nudges and A/B tests are how I make products people come back to, and how I prove it with numbers.

    • AI-native workflow

      I work with Claude Code, Cursor and MCP agents every day to prototype faster and ship more with a small team.

    Let's work together

    I'm open to Product Designer and Design Engineer roles. The quickest way to reach me is email.
