Jan Krüger

Hi, I'm Jan. Here's a (somewhat) condensed summary of who I am, what I know, what I do, and how to reach me.

On the web
Personal blog, my music site (download my songs there)
I'm also on Github.
I'm on Facebook and Twitter, too, but I don't actually do anything there... I'm just wasting space on their servers.
