Senior product designer for 0→1 products and real-time systems — built on a decade of visual craft.

From Balenciaga's atelier in Paris to 3 hardware patents in Berlin to first product designer on a digital gaming platform that reached 13M+ users — 10+ years of learning that great products come from craft, constraints, and shipping.
