First, I devised a design system addressing challenges like inconsistent branding, accessibility, and reusability of components. I created a library of over 100 design tokens and conducted weekly design reviews. Next, we defined our design principles and values, streamlined the design-to-product workflow, and incorporated internationalization best practices. As a result, we successfully launched ARES, demonstrating the power of advanced technology, customer-centric design, and cross-functional collaboration.
