Dear my client!
I read your description carefully.
I have mac application development skill by using cocoa/objective-c.
I'm a just talented ios/android developer with rich experiences - http communication, database(mysql, sqlite), social network integration, service management, and so on...
I have also a hybrid app programing skill such as phonegap.
I wish these my skills will give you full satisfaction.
I hope to work with you.
Thanks.
