Hello, everybody. I have 8 years experience in C\C++ programming. I have started Objective-C programming for iOS (iPhone/iPad) and Java programming for Android from 5 years ago. I can also provide graphics design. Currently, my main tech is Mobile development. I have mastered Objective-C, Java, HTML5, cocos2d, cocos2d-x, box2d, C\C++, C#, PHP, VB.Net. I have developed Windows and Linux programming before starting iOS and Android applications. I knew the structures of system and applications well, during studying the reverse engineering and cracking some applications. I enjoy development and have no problem to satisfy whole customers. I love my job and technology as well as working with my friends. Anybody can contact me and ask for any help. Best luck with you. Thanks.
