1. Finish just one project (not to shiny-perfect, just to functionally complete) and put it on GitHub. This is to show you can finish something. It's a huge risk mitigator if someone can look at your code. Nobody's code is perfect, but some code is always better than no code.

2. Put the rest of the stuff up on GitHub, with suitable disclaimers, e.g. "I was working on this to learn X ..." Everyone understands (well, everyone I like understands) that creative people have lots of projects in various stages of disarray.

3. Target a few small/midsize startups, not the super-hot ones, and spend 1-2 hours to learn their product. I would be THRILLED to get an email from someone who said "I love what you do, here's three things I would like to work on with you to make it better, are you hiring?"

4. Put up front your willingness/unwillingness to relo. If you have remote working experience, give an overview of that. "Worked remotely for company X for two years, with daily standups, weekly sprint meetings, monthly 3-4 day visits, and two visits of 2 weeks duration 2x/year." That lets me know what you're up for.
