I am a software developer currently living in Tomsk, Russia. I received a PhD degree in Computer Science from Tomsk Polytechnic University in 2010. I have been professionally developing C/C++ and PHP software since 2005. I like contributing to open-source and writing programming articles for popular web resources, like CodeProject. Besides writing, I love skiing and watching Formula-1.
