Ian Frost is a UK-based product designer focused on design systems and design tokens — the architectural primitives underneath modern multi-platform design systems. He has been one of the more visible independent voices on the design-tokens-as-source-of-truth approach to scaled design.
His CourseFlix listing carries two Ian Frost courses: Subatomic — The Complete Guide to Design Tokens (the canonical paid resource on design tokens) and AI & Design Systems (the emerging intersection of AI tooling with design-system construction).
Material is paid and aimed at product designers and design-system maintainers responsible for the architectural decisions in their organisation's design system. For broader content, see CourseFlix's UI/UX Design category page.
