Product Manager with 4+ years building regulated, high-stakes products end to end, from customer discovery to shipping and commercial impact. As sole PM for Energieausweis48 I turn complex regulatory processes into simple, automated workflows. My UX research background helps me look past feature requests to the root problem, and I build hands-on with AI tools in my own projects.
