Career advice needed

I'm a technical product manager in Austin with just enough coding chops to look good on TV. (Rails, some Python, Bootstrap for styling, R; doing the Node & Backbone tutorials now.) The code's not good enough to impress anybody on GitHub, but I'll keep plugging away.

Any suggestions on how to increase visibility with hiring managers? PMs don't have anything like a GitHub to showcase their skills.

Appreciate it in advance.
