Teeboxer is a golf simulator that uses over twenty SaaS APIs, including Twilio, which Yuri won the "Coordinating People" contest for by integrating it seamlessly into his application. Teeboxer's technology stack includes Ruby 1.9 and Rails3 on Rackspace's Cloud, with Regenerable data stored in memcached and Redis, and PostgreSQL as the store of record. The front-end uses jQuery and SASS, while Twilio was the most straightforward integration for Yuri, allowing him to focus on other features. Yuri got started with Twilio when he began designing Teeboxer's SMS capabilities, which turned out to be popular among users, and now expects to do more with voice functionality in the future.
