I lead data science and analytics teams optimizing high-stakes marketing and product decisions.
NetherlandsWhat I'm looking for
At Booking.com, I lead data science and analytics for Growth Marketing, managing a cross-functional team that optimizes a €200M+ annual marketing portfolio across channels.
I launched an AI self-service analytics platform with data scientists, analysts, and commercial leads, cutting ad-hoc requests and reporting time by more than 70%. I also led the GTM strategy and measurement framework for WhatsApp launches in India, Brazil, and Mexico.
My work is business-first: I focus on answering the core commercial question, from multi-vertical unit economics and experimentation to value-based app acquisition and centralized business intelligence.
Previously, at WPP x The Coca-Cola Company, I built market-entry and engagement strategies, analyzed social listening data, and automated Google Trends extraction with Python. I enjoy developing people, setting rigorous analytics standards, and helping teams make fast, high-stakes decisions.
