I am proud to contribute to Wikipedia when I have useful content or can add a missing citation.
I have a master's degree in mathematics, which I used to teach at Oakland Community College. I work as a software architect on the Plex Systems ERP solution and from 1998-2014 I was been behind the freeform, weekly music program Outsight Radio Hours, one of the longest-lived Internet radio programs as far as I know.
I am glad when any of this experience allows me to contribute to Wikipedia.
