Josh Rufer attended university and majored in graphic arts. As passionate as he was for his traditional artwork, he found far more enjoyment in the art of human interaction. His first position was as the junior interface designer for a small XP programming group. Without enough work to keep him busy, he quickly outpaced his job title and was promoted to senior user experience engineer. On enhancing his programming skills in Java and C++, he was promoted to the position of junior programmer and again promoted as a senior software engineer.
Always looking for more challenges, he formed a one-man design and software engineering firm called Guy Writes Code. This allowed him to focus his free time on the things that most interested him: designing and development for the iPhone and iPad. He has created several public applications for companies such as Metabahn and Camdilleo Media. He is currently working on iPad-based training and simulation applications, including augmented reality training on the iPad.
When possible, Josh has helped with fact checking and technical editing for books such as Deploying with JRuby by Joe Kutner.
