Three products where the hard part wasn't the interface. A construction CRM with five roles and editorial review, a dual mobile app for private transfers, and a web experience. Each one is documented here as a decision, not a gallery.

I'm a product designer based in Tokyo, with three years as a front-end developer behind me.

I work on the products nobody screenshots for inspiration: CRMs, operational dashboards, booking systems — where the difficulty isn't the visual layer, it's the business logic underneath it. My most recent project was a CRM for the construction industry with five user roles, around 50 interfaces, and permission rules that changed what every single screen was allowed to show. Having shipped React and React Native applications myself, I design inside real constraints and specify work in enough detail that engineers don't have to guess. On that project I stayed on through implementation — mentoring the developer and reviewing each build against the design documentation. Currently studying Japanese full-time in Tokyo, and looking for a product design role in a global team.

expertise

expertise

(1)

Product Design

End-to-end design for complex applications: information architecture, user flows, wireframes, high-fidelity UI and interactive prototypes. Comfortable with products that have many user roles, dense data and heavy business rules.

(2)

Design Documentation & Handoff

Screen transition diagrams, interaction specifications, business rule documentation and component libraries with consistent naming. I write the documentation that removes ambiguity before development starts — and stay available for clarifications while it's being built.

Front-End Development

Three years shipping production web and mobile applications with React, React Native, TypeScript and Tailwind. This is why my design proposals are feasible, and why handoff is a translation rather than an interpretation.

AI-Assisted Workflow

Claude, GPT and Cursor for persona development, requirement clarification, specification drafting and rapid exploration of alternative flows.
