The Twilio Developer Contest was won by David K. Pham with his application Conferous, a simple conferencing feature for businesses. Conferous was built using Ruby on Rails and the Twilio API, which made it easy to develop and deploy quickly. The application took 4 days to build and is aimed at businesses without a single physical location, such as those with remote employees. David K. Pham plans to use the resources from winning the contest to create an online school system that utilizes conferencing functionality, potentially reaching underserved communities.
