I build productsthat move.

I turn ambitious ideas into products people can actually use—from the first prototype through payments, analytics, releases, and scale.

How I build

Across the whole product, without losing the thread.

  1. 01

    Product direction

    Shape the problem, make the tradeoffs, and ship the smallest product that earns its next iteration.

  2. 02

    Mobile and platform

    Build native-feeling React Native products and the TypeScript systems that keep them fast and reliable.

  3. 03

    Money and realtime

    Design payments, wallets, market events, dispatch, and other systems where correctness meets immediacy.

  4. 04

    Release and learning

    Close the loop with analytics, observability, automated delivery, and experiments grounded in evidence.

Open source

The useful parts escape into packages.

Small native modules for problems I wanted solved properly.

Now

Building markets, native interactions, and the systems behind both.

I’m leading GameStock and maintaining open-source React Native packages. I’m always interested in ambitious products, strange technical problems, and people who care about craft.
