BELOW THE SURFACE

Product Designer → Design Lead · Japan localization

Lasting team impact.

More about me ↗
01

Build the foundation.

I design core flows and information architecture that turn operational rules into usable products.

02

Lead through expansion.

As specialties, features, and markets grow, I decide what can extend and what needs to stay familiar.

03

Build capability across the team.

I turn individual experience into design ownership, shared standards, and review practices.
