I am mostly retired, but feel free to chat on my talkpage. If you want help with anything, just ask me or ask the helpdesk.
I rarely touch articles related to my work; If I write something good or bad, blame me, not my employers.
If you want to see some barnstars and related bling, try here.
Some of the things I've worked on:
Updating, cleaning, & adding sources to various Africa, economics, industrial, history, & transport articles; especially ones which are lower on the quality ladder.
Occasionally, I spend a couple of days investigating some long-term subtle vandalism, copyvio, hoaxes, or pov-pushing.
Cleanup of pseudoscience, alt-med, and other fringe articles; working towards neutral coverage on subjects which often have few mainstream sources. Sometimes I try to do similar work for some of the more controversial bits of human geography in the Balkans, and of Ottoman history, and other areas with persistent neutrality problems - though it can be quite wearing.
Occasionally, I hang around at places like AfD, AN/I, and various other noticeboards.
Less often, I create new articles; about 280 so far. Some are a bit stubby, alas, as I can never find time to expand them - there are always other articles elsewhere with more pressing problems. Maersk Triple E class is probably one of the nicest, but I'm more proud of the Ottoman taxation articles as this is an area where en.wikipedia is much weaker - if I hadn't created the Maersk, somebody else would have. Also, I usually leave GAs/FAs &c to other editors.
Dispute resolution &c: I've previously worked on 3O, RfC, and the mediation cabal, though I'm more interested in disputes brought up on other noticeboards and project pages.
