I'm an experienced software developer, especially mobile development. I have 5 year working experience, I worked for many US and European companies. I'm working with Apple technologies, developing a signal processing tool on Mac OSX. I have a good knowledge of Objective-C, xcode IDE, and Cocoa, Core Foundation, Foundation frameworks. I have a good knowledge of Mac OSX and iOS operating systems like the architecture of object files (Math-O), Darwin kernel, etc. Programming with C, C++, C++ templates is my strong point, I have an insight knowledge of STL design such as iterators, containers, algorithms. But beyond the standard library I'm also taking part in other ambitious libraries - boost and xercesc that are superior over STL. I've worked in Windows platform and developing applications using Windows API and MFC. I have travelled and worked with oversea developers, good at communication in English. My favorite programming languages are C, C++ and Java, I have a good knowledge of computer architecture, software development, design patterns and library design. I can read and write UML diagrams for modeling a system, a framework or a library and also database modeling. I'm very passion and curious in searching in security area.

I have a passionate mobile team they can work with any mobile apps or games and we also take a role to develop CMS to support for mobile apps.
