About

As a Senior Consultant with a background in applied mathematics and an Executive MBA at TUM, I combine analytical rigor with strategic thinking. My work focuses on advising clients on AI adoption, leading cross-functional teams, and translating complex challenges into actionable solutions. What sets me apart is a hands-on technical background that gives me a deep understanding of how AI works under the hood, making my strategic advice more grounded, more precise, and more effective. I also bring strong expertise in digital accessibility, from regulatory frameworks like BITV 2.0 and WCAG 2.1 to hands-on implementation and testing.
