    Hey, My name is Jason! I'm American talent living just outside of Richmond, Virginia. I first started working with web applications at age 15. I taught myself PHP, HTML and CSS during my adventures setting up my own online fan-forum for a series of young adult books. More recently, I've focused more on Object Oriented Programming languages like Java and little bit of Objective-C. We live in a world inundated with mobile devices. Exciting things are happening on the mobile front and I love to push the boundaries of what's possible. I've made a number of web/mobile apps for clients in the past and am excited to be working on a number of new projects using public API's for games and social apps. I've very experienced with UI creation and "slicing". I'm familiar and experienced with 9-Patch images and have extensive experience creating logos, UI elements, and layout designs from scratch.  less
