David Zientara is a software engineer and IT professional living in northern New Jersey. He has 20 years of experience in IT and has been an enthusiastic supporter of the free and open source software (FOSS) community throughout his career, beginning with his first foray into the open source world with Slackware Linux in 1995. In the mid-1990s, David became lead software engineer for Oxberry LLC, a digital imaging company headquartered in New Jersey. In this capacity, he played a major role in developing a new software package for the company's film scanners for Windows while also helping maintain Oxberry's legacy software, which had been developed for the SGI IRIX platform. He continued in this role for many years and continues to play a part in software development for Oxberry's corporate successor. In the mid-2000s, David took an interest in computer networking, an interest that led him to learn about m0n0wall and, eventually, pfSense, a fork of the m0n0wall project. His interest in pfSense prompted him to create a pfSense website, http://pfsensesetup.com/, in June 2013.
