About

Make it happen, because no one else will do it for you. I am a Head of MarTech and Technical Architect with over 8 years of experience building and scaling marketing data infrastructure for high-growth global platforms. I operate at the intersection of growth strategy and backend engineering, translating commercial goals into scalable technical infrastructure. I specialize in full-stack overhauls that fix data fragmentation. Currently, I am directing the post-acquisition data architecture redesign and infrastructure migration to unify the stack across Mytheresa, Net-A-Porter, and Mr Porter. My focus is on architectural logic, data sovereignty, and protecting marketing P&L. • Built custom, warehouse-first attribution and tracking frameworks from scratch, eliminating costly third-party MMP dependencies and protecting multi-million euro monthly marketing investments. • Improved overall tracking data integrity by more than 50% and accelerated campaign speed-to-market by 80%. • Reduced technical troubleshooting times by 4x and optimized the integration of a multi-million euro data stack. I lead teams with objective logic, transparency, and empathy, focusing on building high-trust, low-politics environments where developers and analysts have the independence to take absolute ownership. Outside the data stack, I keep my balance through kitesurfing, snowboarding, and exploring the intersection of creative technology and peak performance.
