I'm an iOS / Mac OS Objective-C / Html / PHP / Ruby / jQuery / JavaScript developer for 6 years now with 10 years programming experience. I've created from scratch several successful apps (e.g. Appetize - , Spinlister - , Woblink, Infakt, for more, please check: ). I can help you with UI and UX design. I can create bug-free, well tested applications (unit testing, UI testing). I will help you to publish application in App Store / Google Play and I will resolve any problem in submission or acceptance process. I'm using all available iDevices to test applications (from iPod - iPhone - iPad). I'm familiar with Web Services, 3-party libraries and limitations of variety iOS versions.
