Tokens, primitives, and patterns that scaled across 4 product lines and 60+ engineers.

Four product teams. Three accidental design languages. Globalfair DS unified them under one tokens layer — semantic, themable, and engineered so a button is a button is a button.
Every team had shipped their own primitives. Buttons varied by 4px of padding and seven shades of blue. We needed a system that respected speed without sacrificing coherence.

8 weeks audit + rolling adoption research
"I copy-paste from the last PR. That's my design system."
"I want tokens I can trust — not a Figma of best-effort ghosts."
Adoption rose sharply once docs shipped runnable code, not just anatomy diagrams.
Embedded designer for two weeks unblocked more than any Loom could.
Teams stopped asking for new colors once intent tokens (danger/success/info) existed.
Audited 1,200 components across four products; landed on 38 primitives that covered 92%.
Defined semantic tokens (intent, surface, density) — never raw hex in components.
Shipped docs as a product: live previews, copy-paste code, a11y notes, and migration guides.
Embedded with each product team for two weeks during rollout to unblock in real time.
