I started iOS development in my free time, reading books, and eventually using the game framework Cocos2D to create a simple game app for myself. I then moved onto assisting HoodHot Travel with the development of their Taxi Guides, apps that have over 50k downloads and $xx,000 in revenue.
Later, I consulted for brands such as Macy's, William Grant & Sons, Aveda, and more--creating enterprise iPhone and iPad apps for their portfolios or exhibits.
In my last startup, I also built a mobile web app using Sencha Touch 2, that deployed to both iOS and Android, and the mobile web browsers.
Recently, I've been tackling Swift in a side project, enjoying hacking in the new efficient and terse language.
