Keith Casey is a problem solver with 10+ years of experience in software development and project management.
Keith has seen projects and teams that run like clockwork, accomplishing amazing things, and others that make the Titanic look like a pleasure cruise. He discovered pretty quickly that the only way to avoid the iceberg is to get the right information to the right people as quickly as possible.
Keith started his career at the Library of Congress in Washington, D.C., where he worked to answer the ultimate geek question: "How much data is in the Library of Congress?" During that work, he drafted two of the XML standards still in use by the Library for Audio and Video metadata collection. On the technical side, he developed Fox News' mobile sites (pre-iPhone), from concept to launch, in forty-five days; the voting system for a live musical performance show; the news syndication system for Cygnus Business Media (sixty-five sites across eight verticals); and the Drupal-based syndication system for a professional sports league and its teams.
In 2011, he joined Twilio as a developer evangelist, bringing communications APIs to the world. Over two years he led numerous outreach efforts within the central US and in the larger PHP community. Keith also led many customer-focused efforts at Twilio to help them use their API in new and creative ways, to drive revenue growth and improve customer experiences. Keith currently consults with a range of companies on API design principles, software quality assurance, and software project triage and recovery.
