Handcrafted apps for the realtime web


I build & deploy realtime web applications… everything from live data visualizations to collaborative work environments and multiplayer games.

I also create open source software, travel, snowboard, and produce immersive dance music experiences.

If you need to prototype a new product, improve your user experience, optimize a sluggish application or create something completely new...
