We have a design for iPhone and Android app. App is about mobile payments as an interface for some specific payment machines.
We need somebody capable to create both iPhone and Android app but only the UI part for no less than 12 screens. Registration, Login, product list, shopping cart, payment, shopping cart processing, favorites, show places in a map, guide me there, settings.
Work includes data capture and validation. Whatever data is capture have to be injected into an Object that later will be translated into a JSON stream.
Regarding logistics we need constant feedback (a stand-up call every day in Latinamerica time zone), code artifacts to be pushed into BitBucket repository, code revision will be ran by us and feedback will be sent back.
Clean code (is a must), support for different OS versions and device screen size: iPhone 5 and Android Hooneycomb. No Storyboard based app for iOS.
