About

I believe the best products are built by empowered, autonomous, and well-structured teams. Having evolved from a decade as a Senior Frontend Engineer into 5+ years of leadership at high-growth companies like Vinted and Laiye, I bridge the gap between technical complexity and organisational impact. My Approach: I am hands-off by design. I leverage my technical foundation to steer architectural strategy and remove systemic blockers, allowing me to focus 100% on organisational health, team performance, and cross-functional alignment. Core Impact: • Scaling & Culture: Experienced in growing distributed teams from 4 to 15+ engineers while maintaining high retention and a culture of psychological safety. • AI & Marketplace Innovation: Led squads in delivering AI-powered support systems and ML-infused automation that directly improved operational efficiency for global platforms. • People Development: Committed to building a leadership bench; I've mentored 5 engineers into Senior roles and 2 into Engineering Management. • Operational Excellence: Expert in utilising DORA metrics and feedback loops to optimise delivery velocity, achieving a 25% increase in team output. Based in Amsterdam. Always happy to connect regarding engineering culture, scaling challenges, or the future of AI in product development.
