• Testing (practical): unit/integration tests with Jest or equivalent (Vitest/Mocha/Jasmine) and E2E with Playwright or Cypress; prioritize critical-path and regression coverage, fast-running suites, and actionable CI feedback.
• Performance: code splitting, lazy loading, image/font optimization, Core Web Vitals and Lighthouse budgets.
• Accessibility and security: semantic HTML/ARIA, WCAG practices, XSS/CSRF protection, secure auth/session patterns.
• CI/CD workflows (Git-based PRs, build/test gates) and rapid, iterative delivery.

• Node.js/Express or NestJS; BFF patterns; GraphQL; Storybook; Tailwind or CSS‑in‑JS; Vercel/AWS.
• Observability (Sentry/LogRocket), feature flags, experimentation, and analytics.
