- Build reusable components, custom hooks, and libraries.
- Ensure cross-browser compatibility and mobile responsiveness.
2. Next.js Framework Implementation
- Utilize Next.js features effectively:
- getServerSideProps, getStaticProps, getStaticPaths
- API routes and middleware
- Dynamic routing, layouts, and nested routes
- Optimize hydration, lazy-loading, and client/server data fetching.
- Implement efficient caching and prefetching strategies for faster UX.
3. State Management & Data Handling
- Manage application state using Redux Toolkit, Zustand, Recoil, or Context API + Hooks.
- Integrate with REST or GraphQL APIs from BFF/backend layers.
- Handle errors, loading states, and fallback UI for smoother user experiences.
4. UI/UX & Design System Integration
- Work with designers to implement pixel-perfect UIs aligned with the enterprise design system.
- Integrate components from Storybook or other design libraries.
- Implement accessibility (WCAG 2.1 AA) and responsive design best practices.
5. Performance Optimization
- Monitor and optimize Core Web Vitals (LCP, FID, CLS).
- Reduce bundle size using code splitting, lazy loading, and tree shaking.
- Optimize rendering performance and memory usage.
6. Testing & Quality Assurance
- Write unit and integration tests using:
- Jest
- React Testing Library
- Support end-to-end testing with Cypress or Playwright.
- Participate in code reviews and maintain high-quality, maintainable code.
7. Security & Best Practices
- Implement secure coding practices (input validation, XSS prevention, secure storage of tokens).
- Follow best practices for API integration, routing, and data handling.
- Collaborate with security teams to comply with enterprise security policies.
8. Collaboration & Agile Practices
- Participate in daily stand-ups, sprint planning, backlog grooming, and retrospectives.
- Collaborate closely with React Lead, QA, DevOps, backend/BFF developers, and product teams.
- Communicate technical challenges and propose solutions clearly.
