Their engineering team is supported by a world-class, fully-managed Figma Design System, including design tokens, responsive variants, and component-compliant wireframes and prototypes. This gives engineers a complete, consistent UI blueprint-freeing them to focus on architecture, performance, and behavior rather than recreating UI patterns from scratch.
