About Me

Technical Product Manager with a proven track record of shipping enterprise FinTech and insurance platforms across Europe. I bridge the gap between business goals and engineering execution — leading teams of 8–12 engineers, owning full product roadmaps, and delivering cloud-native solutions on AWS.

Equally comfortable presenting to C-suite stakeholders and reviewing pull requests with engineering teams. Delivered measurable results across claims, invoicing, warranty, and SaaS billing systems.

Fluent in English and German, with direct experience managing enterprise client relationships across Germany, Switzerland, and Austria. Currently completing PMP certification.
