HOW I WORK
Design products, teams, and systems that make complex work feel clear.
I’m Zeke, a product design leader based in Tokyo. My experience spans consumer fintech, enterprise software, robotics, and customer experience—from IKEA Taiwan and ASUS to PayPay, Kyash, and Sales Marker.
Today I lead product design at Sales Marker, while independently building AI apps to stay close to product decisions, prototyping, and the realities of shipping.
