I started by analyzing the three platforms through the lens of their workflows and user needs, conducting a benchmark focused on scalability, accessibility, and visual consistency. I designed over 40 components, categorized by type (brand, basic, custom, extra), all with defined states, clear hierarchies, and applied microinteractions. Each component was fully documented with visual guides and explanatory notes. The final system was delivered as a Figma file and PDF, enabling the dev team to implement and scale it autonomously.
