  Ship production SPAs with robust state/data fetching, routing, optimistic updates, and skeleton/loading patterns.

• Accessibility & Quality:

  Enforce WCAG-aligned semantics, keyboard navigation, focus management, and contrast; write unit/e2e tests and visual regressions.

• Telemetry & Experimentation:

  Instrument UX metrics (latency, drop-offs), feature flags, and A/B hooks; partner on dashboards for usability and adoption.

• Collaboration & Delivery:

  Work with analysts on acceptance criteria, with backend/AI engineers on contracts, and with security on SSO/entitlement UX. Participate in code reviews and release rituals.

• Frontend Stack:

  Expert in

  React + TypeScript

  , modern state/data tools, and routing.

• Styling & Systems:

  CSS expertise (Flex/Grid), component libs and utility frameworks (e.g., Tailwind, MUI/Ant), design tokens, theming, and responsive design.
