About

Passionate CTO with 15+ years of leadership experience in software and data engineering. I thrive at the intersection of people, products, and technology—driving transformation, innovation, and growth. At Effectory, I led the evolution from a tech-supported consulting model to a modern, scalable SaaS platform—introducing AI, optimising team organisation, and embedding a performance-driven culture. I scale teams (from 3 to 8+), architect cloud-native platforms, and drive product strategy in partnership with cross-functional leaders. Previously CTO at FindHotel and a technical leader at ABN AMRO, I bring a hands-on, goal-oriented leadership style rooted in deep technical understanding and product thinking.
