Built and launched the Charge MVNO, which provides LTE data service along with voice and text via a direct relationship with Sprint. Built and launched Charge Messenger, a free messaging application for iOS, Android and web. Built and launched Bolt, a free P2P calling app for Android.
Before founding Charge, I built a number of systems at Twilio that are still in use today, most notably the PHP HTTP application framework that powers Twilio's web properties and many internal applications, as well as the official Ruby library for communicating with Twilio's HTTP API. Before that built and launched RushHQ, an online college fraternity recruitment tool.
