Numerous iOS and Android apps developed independently and professionally, connecting to back-end systems via RESTful web services with JSON-formatted data. Multiple apps ported from iOS to Android. Multiple apps developed from inception through deployment to various app stores. I have significant cross-platform experience developing an app for both Mac OS X and Windows, porting apps from iOS to Android, and maintaining/extending iOS and Android versions of an app. As well as developing desktop and mobile applications for enterprises, I have extensive experience developing independent applications from conception to deployment.
