    Russia - Last active: 16 days ago - Tests: 3 - Portfolio: 7

    For the last 6 years I've been working primary with C++ and technologies/libraries related to it; such as: boost, Qt, log4qt, STL). I have a good knowledge of the old-school C++98/03 as well as modern C++11. Have an experience with VSS, CVS, SVN and Git. But hugely prefer Git. Have about 3 years experience with CMake. Also I have an experience in software architecture and design patterns(GoF, primary). I prefer projects with unit tests and clean code requirements. For the purpose of unit testing I've used Qt tests, boost test and Google test and Google mock. Currently I work with gtest&gmock combination, mostly. So, my primary goal, at the moment, is to apply my developers skills for some challenging software-developing job which being written using the modern C++ language.
