Sean LangSean Lang attends the Milwaukee School of Engineering; he is currently majoring in software engineering. Even though he is a freshman there, he is by no means new to the field. He has been teaching himself software development for the last four years and during this time, he has done extensive volunteer work for open source software projects. These include roots (a toolkit for building web apps), the Jade template engine, nib (a set of utilities for advanced web page styling), and a myriad of smaller projects. In addition to this, he has been doing freelance web designing and consulting, which is especially convenient because it gives him an opportunity to use the open source tools that he has been developing in production.

Also, he had never written a full book before, so he was really interested and excited to know what being an author is like. Read More Read Less
