In this capacity, he played a major role in developing a new software package for the company's equipment. In the mid-2000s, David took an interest in computer networking, an interest that led him to learn about m0n0wall and, eventually, pfSense.

I want to thank my parents, especially my father, for fueling my initial interest in computers and technology, and my mother, for providing constant encouragement.
