I'm an engineer and technical writer, a contributor to Wikipedia for over a year now. In addition to my experience in electronics, I have interest in and knowledge of history and general science. More specifically, my science interests include anthropology, archaeology, cognition, evolution, and physics.
Contributions to Wikipedia
As of this date (May 25, 2007), I've created 9 totally new articles and edited 104 others (20 major edits and 84 minor edits, per my classification scheme — which doesn't match what Wikipedia will say.) This excludes talk pages and experimentation on my own pages. Although the entry for "Wikipedia Tutorial" actually subsumes 9 separate pages, I did the same thing to each: unifying the formatting of the navigation features at the bottoms of the pages, so I'm counting this as one page.
For those interested, here is a detailed account.
