My Role

Designed the full mobile experience: onboarding flow, schedule browser, attendee profiles, and digital badge feature. Built a component-based design system in Figma aligned with the React Universe brand. Event app that people actually used. 63% adoption, 67% connected via QR badges, 45% created personalized profiles. Built on React Native with Liquid Glass — designed to scale beyond a single event.

Outcome

Worked closely with React Native developers during handoff and QA to ensure pixel-perfect implementation. App launched on the App Store and Google Store ahead of the conference.
