To support Trackap's technical needs, I developed a robust design system from the ground up, strictly following Atomic Design principles. The kit is organized into a clear hierarchy—ranging from foundational Styles (typography, colors) to complex Components and Templates. Beyond the visuals, I focused heavily on the Developer Experience (DX) by integrating precise usage guidelines and a live changelog. This structure bridges the gap between design and code, serving as the single source of truth for the product team and eliminating design debt.
