Hi, I'm Hans Gerwitz and you won't find much from me, here.
When I grew up and wrote software for a living, we used CVS. When I started contributing to open source projects, they used Subversion. By the time git came to dominate and we all accepted GitHub as infrastructure, I had long since ascended beyond actual work.
Still, I continue to code and you might find something interesting in my public repos. ¯\_(ツ)_/¯
