About
I weave my love for delightful interactions with technical understanding.
My background spans product management, visual design, UI/UX, and front-end development. This multidisciplinary perspective helps me connect user needs, business goals, and technical realities to create products that are both thoughtful and feasible.
At Rakuten in Tokyo, I led UI/UX work across customer-facing and internal products, developed scalable design systems, and worked closely with cross-functional teams in both Japanese and English.
