John Earl Clark - Sencha Touch 2 Mobile JavaScript Framework

John Earl Clark holds a Master's degree in Human Computer Interaction from Georgia Tech and an undergraduate degree in Music Engineering from Georgia State University. He and his co-author, Bryan P. Johnson, worked together at MindSpring and, later, EarthLink; starting out in Technical Support and Documentation before moving into application development and, finally, the management of a small development team. After leaving EarthLink in 2002, John began working independently as a consultant and a programmer, before starting Twelve Foot Guru, LLC. with Bryan in 2005.

He has been working with Sencha Touch since its first beta releases. He has also worked with Sencha's ExtJS since its early days when it was still known as YUI-Ext. He has also previously written a book with Bryan Johnson called Sencha Touch Mobile JavaScript Framework, Packt Publishing.

When he is not buried in code, John spends his time woodworking, playing guitar, and brewing his own beer.

I would like to thank my family for all of their love and support. I would also like to thank Bryan for his help, patience, and continued faith in our efforts.

Bryan P. Johnson is a graduate of the University of Georgia. He went to work for MindSpring Enterprises in late 1995, where he met his co-author John Earl Clark. At MindSpring and later, EarthLink; Bryan served in multiple positions for over seven years, including the Director of System Administration and Director of Internal Application Development. After leaving EarthLink, he took some time off to travel before joining John to start Twelve Foot Guru.

Bryan has worked with Sencha's products since the early days of YUI-Ext and has used Sencha Touch since its first betas.

I would like to thank my family for their support, and my co-author John for his patience during the creation of this book.

Paul David Clegg is a software engineer and part-time photographer from Manchester, United Kingdom. He attended the University of Manchester from 2006-2010, graduating with a B.Sc. in Computer Science and, shortly after, an M.Sc. in Software Engineering. Web-based and mobile technologies have been the main focus throughout his career, although semantic systems and Augmented Reality have also played their part.

While studying at the university, he looked at how Augmented Reality could be used in a location-based service. In 2010, he produced a content management system for AR mobile apps, turning Google SketchUp models into points of interest that could show the location of the user at full scale using Augmented Reality on a mobile device.

He moved on from studying to developing a web-based mobile platform serving dynamic content to mobile apps for iPhone and Android. The platform used popular technologies, such as Sencha Touch, Cordova, and Zend.

After working with various creative agencies around the country, he eventually started his own company in 2012, Gather Digital. The company specializes in scalable digital asset management systems and adaptive web development.

He lives in Birmingham, UK, with his wife and two children.

For Jenny, Sophie, and Elliott. With love.
