Yes, that is a domain and email therefore works: info (at) herzste.in
My real name is Georg Schneeberger and georg (at) schneeberger.de could also work, because my father claimed it many years ago. I find Herzstein more fitting for the projects I do right now. I studied computer science and my focus was on AI and languages. I play League of Legends since my high school by the name Herzstein. I have a reasonable knowledge in game design. I am also interested in crypto-currency. More you find at About and at Herzstein.dev
