Twitter's Horizon Design System

Designing at scale

Twitter’s design system, Horizon, was relaunched to focus on universally accessible UI, user-driven content and dynamic visuals.

As Product Design lead for Horizon, I led on cross-platform consistency, defining success, lobbying leadership, designing processes and mentoring our Senior & Staff Designers. My research showed that Horizon saved ~70% of a designer’s time, most using the library daily.
