Most of the relevant contact stuff is on the "home" page, but everyone always has a contact page, so I'll have one, too. There's an email link in the footer. My Twitter and Github points of contact are on the aforementioned page.
If you're interested in hiring me, the best way to do that would be by heading over to exnilio, my company's site, and getting in touch there (for instance, emailing firstname.lastname@example.org), but you can use the link in this here footer to email me personally as well.
Feel free to get in touch for any other reasons, also!
