I have immense experience in iPhone app development and playing around with the internals of an app. This gives me a lot of strength to understand what the best flow and design will be. Also, well versed with the iOS design principles. Have worked with most of the internal iOS frameworks and have developed frameworks of my own. Also, used features like on app Database interaction (eg. SQLite), REST communication with the app server, app designing, UI events trapping, notifications and more.
