Amazon Glow: make believe, for real

A first-of-its-kind “phygital” device that turned video calls into shared play. I owned all core platform UI—onboarding, calling and activity browsing—across the child's device and the caregiver's app, and authored the dual-plane interaction model and design tenets behind it.

Tangrams: the game that greenlit the Glow

The Glow’s hero activity, and my own concept end to end—Game Design Document, difficulty curve, and the “Guided Play” affordances that let a remote adult hint without taking over. I 3D-printed the first piece sets, hand-labeled 400+ pieces for the computer vision, and ran 41 playtests.

Clarity: dense reporting under pressure

A full UX overhaul of Amazon's internal workforce reporting platform—a simplified core for everyday managers, an advanced control panel for power users, and Clarity Assist, an AI chatbot for querying team data in plain language. 20 interviews, CAB validation, testing with 40 employees.

Bringing empathy to scale

While the heart of UX will always be human-centered, I’m embracing the AI revolution to stay ahead of the curve—redefining the design process by using the latest technology to bring empathy to scale.

That means leading teams through ambiguity, building the system that lets a team move fast, and staying close enough to the craft that the last 5% still gets done well.
