Linh Nguyen Agency Contractor

Experienced iPhone/Android Developer

Vietnam - Tests: 4 - Portfolio: 8

Programming has been my passion before I become a professional programmer. When I was a student, I realized that knowledge from university was not enough for me to become a professional programmer. So I took some tests to become probationary student of a big software company. Gradually, I became an official employee of that company. Here, I could get lots of knowledge and experience. After that, I continue changing some companies as well as positions for learning and experience. So, although I have just graduated 2 years ago, I have about 5-year-experience. Now, I am confident of working for myself. My skills and experiences are following: Mobile Applications + iPhone/iPod/iPad, Android apps development + Web Service, Ajax, XML, JSON, RSS, SOAP, WSDL + MySQL, SQLite, HTML5, PHP, JSP, JAVA, Script, CSS + Facebook, Twitter, LinkedIn, Pinterest, Google Plus + Google Map Service, Foursquare + CoreData, CoreGraphics, Animation + Apple Push Notification + Socket programming Web applications + PHP + CakePHP Cloud computing + Google App Engine + Amazon web services
