Software development is Chris's greatest passion. He's always looking for something new to learn. Currently a senior developer, his goal is to be a software architect. He has a master’s degree in computer science and has published papers and given many talks about computer science. He's worked with companies like HP, Softtek, and Herbalife on critical business apps, so he knows how to work with distributed teams and high responsibility.
