How We Built a Design System Serving 200+ Projects
Aisha Patel
Head of Design
Building a design system is one thing. Maintaining it across 200+ projects with different brand requirements is another challenge entirely.
The Foundation
Our design system, Nexus DS, is built on three pillars:
1. Tokens: Colors, typography, spacing — all defined as design tokens 2. Components: Reusable UI components with built-in accessibility 3. Patterns: Common interaction patterns and page layouts
Scaling Strategy
The key to scaling is forced extensibility. Every component accepts theme overrides through a standardized API, so client-specific branding doesn't require forking the system.
The Numbers
Since adopting Nexus DS:
- Design time reduced by 60%
- Development time reduced by 45%
- Bug reports down 35% (accessibility built-in)
- New developer onboarding cut from 2 weeks to 3 days
Lessons Learned
The biggest lesson? A design system is a product, not a project. It needs dedicated ownership, regular updates, and a governance model that balances flexibility with consistency.
