Building a design system rarely starts from scratch. More often, you join mid-flight—surrounded by existing patterns, tools, and habits. In this talk, I’ll share how we spent our first nine months evolving Wolt’s design system: introducing a full token architecture, creating a scalable component library, and aligning teams—without disrupting ongoing work. You’ll learn why thinking in orbits, not timelines, helps you navigate inherited systems, and how to design for both today’s needs and the next decade of growth.
