Summary
👤
Senior🎓
Top SchoolJohannes Lamers is a Senior Lead Product Designer based in Amsterdam with nearly 20 years of hands-on experience turning complex problems into clear, measurable products. He combines strategic consulting and systems thinking with day-to-day design and delivery, having led award-winning healthcare tooling (Red Dot 2025), high-growth retail apps, and global e-commerce optimizations. His work drives tangible business outcomes—examples include a 350% increase in add-to-bag for Maisonette’s app, a 12% lift in PDP-to-cart conversion for adidas, and a faster site across 20+ markets. Comfortable bridging strategy, engineering and product, he often steps into troubled projects to realign teams and rescue delivery. Less obvious: he mixes studio-level end-to-end craft (from brand to implementation) with enterprise-scale rigor, making him equally effective sketching concepts or shipping production systems.
