  • Integrate with backend APIs for ticketing , LMS deep links (Disprz) , CRM / ERP views.
  • Add analytics events, feature flags, and guardrails (auth / session, rate-limits at BFF).
  • Write tests ( Jest / Playwright ), participate in code reviews, and contribute to CI.

Must-have skills

  • 1–3 years with React / Next.js and TypeScript (SSR / ISR fundamentals).
  • Strong UI engineering : Auto Layout-like CSS , Tailwind or CSS-in-JS, form patterns.
  • State management (React Query / Zustand / Redux) and API integration.
  • Basic testing (Jest / RTL / Playwright) and Git / GitHub workflows.
  • Familiarity with OIDC / OAuth flows from the frontend (session handling, token refresh).
  • Accessibility awareness (focus states, semantics, keyboard paths, color contrast).
  • Nice-to-haves

  • PWA (Workbox), web push , performance profiling (Lighthouse / React Profiler).
  • Storybook and design-system contributions.
  • Exposure to React Native (helps collaboration with mobile).
  • Error / perf monitoring (Sentry) and analytics (Mixpanel / Amplitude).
