AI Product Owner · 506.ai
I am an AI Product Owner at 506.ai, where I shape the 506 AI Platform. I am based in Upper Austria. I started out in performance marketing and tracking, taught myself to code, and moved into product and engineering. On the side I build things for the web: right now a site about a Magic: The Gathering format, an app for learning German and a tool that keeps track of the apartment market.
