We have 3 main teams that handle three library categories per team, such Foundations, Components, and Assets & Illustrations. As a member of the team that handled Foundations, I was responsible to define the foundation's elements such as color palette, typography, layout, corner radius, shadow, spacing, and design tokens. Besides that, I have to ensure that foundations library is aligned with the other teams' libraries (components and assets library). Throughout the development process, I worked closely with the other teams to ensure consistency across team and to avoid any overlap or confusion.
