Hello!
I am the Webmaster & IT Director for The Mars Society. I am both a volunteer and a paid staffer for the Mars Society. (I volunteer much more time than I am actually paid for, and the pay is very minimal based on the IT consulting skillset I have. Bottom line, I help the Mars Society and other groups because I am very passionate about their causes, not because it's financially worthwhile to me.)
I am also the Webmaster & Director of Communications for The Mars Foundation and a former Vice President & Webmaster and current member of The Moon Society. All three of these organizations I just mentioned are partnering on the Marspedia wiki, for which I serve as the Vice Chair of its Governing Council. I am a volunteer for these other groups and am not paid anything.
I also work at a small company that does technical consulting on software development, business intelligence, and data warehousing. That is my day job.
I am usually on Wikipedia making corrections to Space-related topics. I have also added a couple of articles in the past. The edits I make on Wikipedia are both for personal interest and based on the needs of my position at the Mars Society and the other groups. For example, recently a Wikipedia editor made updates to the Mars Society article and asked me to review for accuracy, which I did.
Best.
