WELCOME, - My experiences is : * Android App development in the Java programming language using the Android Software Development Kit,(Eclipse, Android studio, Xamarin, C#, etc) * iPhone, iPad App development in the Objective-c(including Cocoa) using the Xcode, * Website building in Ruby on Rails,(Including PHP, HTML5, etc) ... Also, I can build back-end and API from database. I'm ready always for your job and I can start immediately. Let me know if you need any help with any of that. I hope to work with you. Thank you!
