Problem Statement
When multiple product teams ship on the same brand, UI fragments fast: every team rebuilds buttons, inputs, modals, and tables slightly differently; accessibility is inconsistent; theming/rebrands require touching dozens of repos; and design ↔ engineering drift erodes trust. At millions of users across many product verticals, that fragmentation becomes a real cost in velocity, quality, and brand coherence.
Proposed Solution
A single, enterprise React + TypeScript design system of 70+ accessible, theme-able components, documented in Storybook and adopted across all product verticals. Teams compose features from a shared, tested, accessible component vocabulary instead of reinventing primitives — so the UI is consistent, accessible by default, and re-themeable from one place.
Full Solution Details
- 70+ components — the full primitive + composite set (inputs, buttons, modals, tables, navigation, feedback, layout, etc.).
- Accessibility built in — ARIA semantics, keyboard interaction, and focus management baked into each component so consuming teams get a11y for free.
- Theming — token-driven, theme-able components so brand/dark-mode/vertical-specific looks come from configuration, not forks.
- Storybook — interactive documentation and a visual contract for every component, doubling as the design ↔ engineering handshake.
- Org-wide adoption — used by every product vertical, serving millions of users.
Technical Documentation
React + TypeScript component library with Storybook as the documentation and development surface. The system is built around design tokens (so theming is centralized and a rebrand is a token change, not a code sweep), strongly-typed component APIs (predictable props, variants, and slots), and accessibility as a non-negotiable per-component requirement. Distributed as a shared package consumed across many product repos, which makes API stability and versioning discipline first-order concerns — a breaking change ripples across every vertical.

Smart Architectural Decisions
- Token-driven theming. Centralizing design decisions in tokens means rebrands, dark mode, and vertical-specific themes are configuration — not a fork per team — which is the only way theming scales across an org.
- Accessibility as a component invariant. Building a11y into each component means every consuming team inherits correct semantics/keyboard/focus behavior automatically, raising the floor for millions of users.
- Storybook as the contract. Interactive docs keep design and engineering aligned and make the system self-service, which is what actually drives adoption across many teams.
- API stability discipline. As a shared dependency of every vertical, the system treats versioning and backwards compatibility as primary concerns — the hallmark of platform-level engineering.
Impacts
Unified the UI across every product vertical for millions of users: consistent, accessible components, centralized theming, and faster feature delivery (teams compose instead of rebuild). A genuine platform/infrastructure contribution rather than a single app.
Demonstrated Skills
Design-system / component-library architecture at enterprise scale; accessibility engineering (WAI-ARIA, keyboard, focus); design-token systems and theming; Storybook-driven documentation and design-engineering collaboration; shared-package API design, versioning, and backwards-compatibility discipline; React + TypeScript at scale.
