Operationalizing consistency across web and mobile through a three-tier token architecture and sustainable governance.
Context
As Fullscript expanded, I played a key role in the evolution of Aviary, a multi-platform design system. I led a strategic audit of the existing library to consolidate components and streamline our scope for a multi-platform environment. By architecting the token structure and documenting its application, I helped create a scalable framework that synchronized design and engineering workflows across web and mobile.
Challenges
Platform Expansion
A mid-project pivot to native iOS required a flexible architecture that could serve both web and mobile teams from a single source of truth.
Legacy Cleanup
The codebase was filled with custom components. I partnered with Engineering to audit these patterns, consolidating or eliminating them to ensure a clean foundation.
High-Velocity Delivery
To meet the September 2025 launch date, I organized weekly rapid-feedback sprints to identify and prioritize the most critical components for launch.
Scaling with intent
This architecture allows a single brand update to instantly update over 50 components. This automation removes manual maintenance and ensures that design and code never drift apart.

Accessibility & theming
Cross-platform logic
To solve for platform parity, I partnered with native engineers to align our documentation and build approaches that accounted for platform-specific patterns. This created a single source of truth that cut development guesswork significantly and resulted in 4x faster handoff during high-stakes prototyping cycles.
Conclusion
This project was about more than just building a library. It was about creating a sustainable model for unified product development. By stress-testing every component state and focusing on accessible, reusable building blocks, I provided a foundation that allows the company to scale without sacrificing quality or speed.
