    I've worked as a full-time C++ and Bash programmer for over 4 years. I work on linux only (or crossplatform applications). I have strong knowledge in C++, stl and multithreading. My primary tools for development is git (github, gitlab), vim, gdb, and sometimes qtcreator. Also I have successfully completed some small python projects on odesk. I have some experience in Boost, asio, networking, pcre, pthreads, Qt, perl, OpenGL, SQL. I haven't got a lot of free time these days. About 20-25 hours per week. And since I am interested in small jobs I can accept offers in fields that I am not really strong in: - Python; - Web development (python, flask, django); - scraping; - Qt; - deb packaging; - d3.js; - aws and/or vps administration.  less
