Hello! I am πr2 (t • c). I am a volunteer on the Wikimedia projects, the most well known of which is Wikipedia. Here on Meta, I work on many different things, including technical and translation-related matters. Please contact me here (on Meta). My native language is English, but I also know some French (fr-1), and some Italian (it-1). If you have an urgent problem on Meta or a small global sysop wiki and would like to contact me in another language, I may be able to understand and help you. I will probably not be able to reply in that language, but I'll at least try to say "hello". :) I know a little of many other languages, but not enough to contribute much of value to projects in that language.
I am a global rollbacker and a global sysop. This means that I can revert vandalism and spam on all wikis, and that I can perform admin actions (like deletion) on some, but not all, small wikis. In addition, I'm an admin and a translation admin on Meta, as well as on MediaWiki.org (which is also a global sysop wiki) and Wikimedia Outreach (but I'm not very active there). I try to be fair, nice, and generally pleasant as an admin, and I usually prefer meatball:SoftSecurity. If you need admin help here, you may either contact me directly or write the request on our help page. I have SUL enabled, which means that I own the account with this username on all public Wikimedia projects (see sulutil:PiRSquared17). I am also "PiRSquared17" on the Wikimedia Foundation wiki, which is closed to public editing.
