Like some people here I've written a lot of proprietary code used by millions of people but have (almost) zero code in public repositories. I do see the value in having some sort of "portfolio" piece to show off your skills and if I have spare time (and I never seem to have much) I may do a small project and put it in the public domain. Obviously there's a limited amount of time that I can put into something like that.
