I get most of work through networking. Otherwise, I've found Reddit and Facebook to be extremely helpful. Far more than LinkedIn or dedicated job boards.

How do I go about?

I introduce myself, mention relevant experience, list references. And, mind you, I'm not a dedicated opensource contributor. Hell, even my public GitHub repo is dated and not that rich. Again, my target market are not tech companies per se. I prefer being the tech guy in a non-tech company.

Mis dos centavos.
