## Project

Leading design system migration to theming tokens for brand refresh, acquisition, and dark mode capability.

I led the move of five libraries onto Figma variables and semantic tokens, so that design matched code. Theming became a switch instead of a redraw, which is how the brand refresh, dark mode, and Discover reached every screen built on the system.

- Before this work: Dark mode painted by hand, screen by screen, with anything missed left glaring white.
