In the last 7+ years, I have helped 10 companies build mobile solutions. Most of them I have developed from scratch, so I know how to design application architecture and write clean and simple code. In addition, I have maintained legacy code and am very familiar with debugging and refactoring. Client’s satisfaction and working software are my priority targets. • Native platform: Objective-C, Swift, Java,C#,C,C++ • Cross platform: Xamarin, Phonegap • Web service : JSON, RESTful, Parse, Amazon • Chat & Messaging : XMPP, Jabber, Quickblox, OpenTok WebRTC • Database : MySQL, PostgreSQL, MongoDB, SQLite, Oracle • Social Service Integration : Google+, Facebook, Twitter, Linkedin, Instagram, Youtube • Cloud services : AWS EC2, Dropbox • Sharing source code: GitHub, BitBucket
