Don't focus on the end goal, focus on the journey. I'm a self-taught web developer (used to be a self-taught designer) and I learned my way through development by simply building stuff. I've had stable jobs for over 5 years now.
Once you've built some useful projects (I built Backbone Todos amongst other things), people are going to find you through them and contact you with opportunities all the time.
You've already started putting your work out there on Github, now you just need to market yourself a little better. a Github account isn't enough. Blog about your experience, build a Twitter following and other promotion techniques.
Maybe extract some smaller bits out of your bigger projects. Those are usually more useful and get more popular quickly. Abstract some of that application-specific code and release it. It's both an exercise in programming and marketing.
