I build and maintain design systems that hold up as a product scales, not just a static style guide that goes stale in three months. That means components, documented usage rules, and a system engineers actually pull from instead of reverse-engineering from static files. What's included:

Component library — Reusable, documented components in Figma (and Storybook, if the stack calls for it).

Usage guidelines — Rules for spacing, states, and composition so the system doesn't fragment as new features get added.

Governance — A lightweight process for adding to the system without introducing inconsistency.

Handoff support — Ongoing collaboration with engineering as the system gets built out.
