Wikimedia projects 
I support the corpus of wikimedia projects by serving as a steward for the Wikimedia Foundation. As a wikimedian, I am most active on English Wikipedia, where I am a sysop, bureaucrat, oversighter, and checkuser with over 45,000 edits. I am also a sysop here on meta, a sysop and oversighter on the commons, and an OTRS volunteer. I can often be found on IRC as
Avi|work, or some variant thereof, usually in the #wikimedia-stewards, #wikimedia-commons, #wikipedia-en-spi, #wikipedia-en-admins, #wikimedia-privacy, and #wikimedia-otrs-en channels. Please feel free to drop me a line or a PM if there is anything I can do to help.
I edit other projects besides EnWiki and Commons, and such edits include the actuary article on Simple English wiki, and the Matthew Cooke Manuscript article on wikisource, and I like to add appropriate free-use photos to articles, such as biographies, on smaller wikis using interwiki links. As I have the username Avraham for SUL, my matrix of accounts lists those projects where I have accrued responsibilities other than that of editor.
My activities specific to Meta include participating in meta-wiki policy discussions and keeping an eye on what policies and changes are being discussed that will affect all wiki-dom.
