enwiki is my home wiki, but I have a global account.
I am identified with the Wikimedia Foundation, as per the Identification noticeboard.
What I do
I've occasionally contributed to different Wikimedia projects (such as MediaWiki) since February 2010, but haven't contributed earnestly until now.
enwiki, I participate in WikiProject Articles for creation. I've also fought vandalism with Twinkle and Huggle, which is why I have Rollback.
Last but not least, I run ¯\_(ツ)_/¯ ShrugBot. I have no idea what it does, but it's definitely open source when the time comes.
