At Booking.com, I lead a team of 8 data scientists and analysts and own the measurement and investment strategy behind more than €600M in annual Metasearch ad spend. I designed a cross-platform bid-and-budget model that delivered 500,000 additional bookings per year at stable ROI.
I co-initiated Booking.com's GenAI agent program for performance marketing, originated its performance-health-monitoring use case, and own the product roadmap. The agent is used across our area for knowledge lookup, analysis, and performance investigations, with human quality control during testing.
Earlier at Booking.com, I built an early-warning tool that caught experiments whose aggregate results hid harm to customer segments. At the University of Regensburg, I built an ML-based decision support system that cut tender preparation time from weeks to days. My PhD in machine learning and mathematics background inform my work in experimentation, causal measurement, and investment optimization.
