About

I make complex products easier to use.

At a satellite data company I've built the map rendering and streaming responses behind an AI chat product, and a 3D orbit simulator.

Before that, marketplaces and websites; internally, admin tools and a design system.

The domain keeps changing. Making complex state usable doesn't.

  • Canvas & 3DMap engines, Three.js scenes and 2D canvas overlays that stay smooth with a lot on screen.
  • Real-timeStreaming chat, connections that reconnect on their own, and screens several people share at once.
  • Product flowsFlows with many steps and more exceptions: sign-in, approvals, ordering, sign-off, CMS.
  • Systems & servingDesign systems, monorepos, i18n and quality automation, including raster and vector tiles when a product needs them.
  1. MediaHow people experience things on screen
  2. InteractionHow that screen moves and responds
  3. EngineeringThe systems that make it work in production

I've always been drawn to how people experience things on screen. Now I build the systems that drive those experiences.
