Design System

Enterprise design system with 70+ accessible, theme-able React components serving millions of users. Adopted across all product verticals.

Built and maintained a React + TypeScript design system of 70+ accessible, theme-able components adopted across every product vertical, serving millions of end users with consistent UI and faster feature delivery.

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.

Notes

  • Scale + impact: "70+ components, millions of users, every product vertical" is platform-level work — it demonstrates influence across an entire org, not just one app. This is often the single most senior line in a portfolio.
  • Right hard problems: token-driven theming, baked-in accessibility, and shared-package API/versioning discipline are exactly the concerns that separate a design system from a component folder.
  • Cross-functional signal: Storybook-as-contract shows the author can drive adoption and align design + engineering — a leadership/platform skill.
  • (Enterprise/internal work — no public repo; assessed from role description and the system's stated scope.)
