High-performance GraphQL | ReactNext 2016
https://www.youtube.com/watch?v=c35bj1AT3X8A talk that was given at ReactNext 2016 about optimizing GraphQL performance.

Browser LAN Party! | CampJS 2016
https://www.youtube.com/watch?v=CQNwo2yXp5oA talk that was given at CampJS 2016, Sydney, Australia. The talk introduced my effort to build a multi-device, serverless, multiplayer game. The game uses WebRTC to connect multiple mobile devices to a central desktop "console" and does so without a traditional signaling server, but direct WebBluetooth connection.
The talk reviews both WebRTC and WebBluetooth and how a real-time ad-hoc connection can be established over the web.
