Every feature was designed twice: once in Figma, then again in code. Specs drifted as engineers re-interpreted spacing, color, and states, and each team re-solved the same patterns. Rework was the tax on every release.

I built the system as production code, not documentation about code: design tokens, accessible React components, and usage patterns co-owned with engineering. Designs reference the same components engineers ship, so a spec is a contract instead of a suggestion. Four legacy component libraries rolled into one shared React and Figma architecture, with Storybook as the engineering source of truth.

Cut design-to-dev rework by 50% and gave feature teams a shared vocabulary. New surfaces compose from existing parts instead of starting from a blank canvas. The system now underpins AI, outreach, privacy, and core application surfaces across the platform.

Screens and artifacts for this workstream are being prepared for publication. Most of this work lives behind carrier NDAs.
