Assemble a design system in Figma for the product team

Our product team has grown rapidly, and in that time our interfaces have diverged from each other. Buttons, forms, and cards look slightly different from one feature to the next, spacing is inconsistent, and each new mockup essentially starts from scratch. We're looking for an experienced product designer who will build a single source of truth in Figma: a real design system that our designers and frontend developers can rely on every day. The goal is speed and consistency: building a new screen should mean dragging ready-made branded components, not redrawing them from scratch.

The system should be built on design tokens so that color, typography, spacing, radius, and shadow values are stored in one place and updated globally. We expect a complete library of reusable components with variants, Auto Layout, thoughtful constraints, and clear interactive states — everything neatly structured and named so the team can instantly find what they need. Documentation is equally important: usage rules, "do's and don'ts" examples, and a handoff page that connects tokens and components to what gets implemented in code. Please send portfolio work showing already-launched systems.
