Nam is a full-stack engineer that dabbles in many parts of application development. The stack he works with includes, but is not limited to, build systems, databases design, end-to-end testing, web service development, and web application development. He has a little bit of OCD when it comes to the quality of the work—he believes that a complete code should not just work, but also be clean and maintainable.
