Persona Design System

Persona Design System is a public open-source library used as the shared foundation for designing and building products across the Privy ecosystem.

After the first release, I was asked to continue the next iteration as the design system team became smaller and the library needed to better match current product, tech, and feature requirements.

Because the system had not been updated for a while, several parts were no longer aligned with how the team currently worked. Some assets were outdated, some components had implementation issues, and the file had grown heavier than it should be.

The challenge was not only to refresh the system visually, but to reduce unnecessary weight and improve component efficiency without breaking the existing ecosystem.

I started by remapping components, variables, and styles based on current usage patterns, then reorganized the library structure to make it clearer and easier to maintain.

From there I introduced newer Figma capabilities such as variables and slots, fixed component issues, and tested each pattern one by one before publishing the updated library.

The result was a cleaner and more up-to-date system that better supports the design system team's current workflow and reduces friction when maintaining shared assets.

Persona v2 gives the team a lighter library, clearer structure, and more relevant foundations for ongoing product work.
