Have you actually tried to get hired? If you've never been through any technical (or even non-technical) interviews, you'll likely have a hard time.
So are you Un-hireable? Probably yes. But can you become hireable? Absolutely yes, but with necessary effort.
Start applying. With a list of successful projects like that, you'll get some people taking the bait. Go through interviews, even if you'll fail. Especially if you aren't even interested in working for them. You still get something out of it (practice), which will help you the next time you interview again. Eventually, that next time will be a place you actually want to work at.
(Also, listen to the other comments here about learning version control and doing open source. Those will all be helpful.)
