At UNOWHY, I built a unified design system across SQOOL, SQOOL Extend, SQOOL Protect, Hi SQOOL and the corporate brand. The Figma architecture was straightforward: shared foundations, brand-specific tokens. The hard part was getting five product managers to agree on shared components. I spent more time in alignment meetings than in Figma. The system cut design time by 60%, but only because the team trusted it.
