Overview
Four product teams, three platforms, one fragmented user experience. Meridian was built to unify them without slowing anyone down.
Approach
Started with a token audit across all four codebases to identify divergence points. Built a shared token layer first, then components, then documentation.
What Made It Work
Each team had a nominated 'system ambassador' who attended weekly syncs and carried decisions back. Adoption was opt-in and incremental — teams migrated page-by-page, not all at once.
Scale
340 components, 2,100 Figma variants, 98% Lighthouse accessibility score across all components.
