Design System Architecture
A comprehensive design system built from the ground up, featuring tokens, components, and documentation. Shipped to production serving millions of users.
The Challenge
The team was struggling with inconsistent UI across multiple products. Every new feature meant reinventing the wheel, and design-dev handoffs were painful.
The Solution
I led the architecture and development of a unified design system that could scale across web and native platforms.
Token Architecture
The foundation is a multi-tier token system:
- Core tokens - Raw values (colors, spacing, typography)
- Semantic tokens - Contextual meanings (text-primary, spacing-page)
- Component tokens - Scoped to specific components
Component Library
Built with:
- React for web
- React Native for mobile
- Storybook for documentation
- Testing Library for accessibility testing
Results
- 40% reduction in design-to-dev time
- 60% fewer accessibility issues
- Consistent UX across 5 products
