How a design system scales

One token set, four platforms.

  1. 01

    One token

    color.brand.primary. One colour decision.

  2. 02

    One component

    The token becomes the primary button.

  3. 03

    One screen

    The button ships inside the sign-up sheet.

  4. 04

    Every platform

    Web, connected TV, Android and iOS. Change the token once and all four follow.

Travel, photography, drone flying, making

Off screen I travel, shoot and fly. Every photo here is mine, and the settings under each one come from the file the camera wrote.
