Audited existing interfaces and libraries and produced an inventory of patterns, disparate components, and tokens; engineered a new design system for enterprise scenarios: tokenized typography and spacing, semantic color roles and states, dense desktop data tables and forms, full keyboard navigation, accessibility and contrast compliance, legibility at small UI scales; built a component library (registries/lists, forms, modals, process steppers, notifications, autocomplete, pagination, date/time pickers) with a unified state matrix and adjustable density; published a documentation site with code examples, best practices, and anti-patterns; established release governance (design reviews, release train, RFC), linters and team presets, and component usage metrics; prepared a migration plan and playbooks, starter templates for rapid product bootstrapping, and Figma libraries wired to tokens and components; outcome — a single system that reduces screen build time and layout defects, increases predictability of internal tools, and accelerates onboarding of new teams
