About the Reviewers

Joey deVilla has worked on all sorts of projects, such as creating Olympic athlete training software, CD-ROM directories for every mall in America with Visual Basic, Python-powered gift certificates, travel agency websites, the frontend for the censorship-thwarting project Peekabooty in C++, Duke of URL in PHP that suggests domain names, and a failed social networking app for frat dudes and dudettes in Ruby on Rails. He's also done some technical evangelism for OpenCola, Tucows, Microsoft, and Shopify. He's currently stirring up trouble in the mobile industry, and when he's not doing that, he's stirring up trouble playing Nine Inch Nails, AC/DC, and Britney Spears on his accordion.

He's worked with many different languages and frameworks over the years, but his favorites are Ruby, JavaScript, and Objective-C.

Scott is the founder of corgibytes (http://corgibytes.com), a consulting company with a focus on legacy applications.
