Key Responsibilities

React.js Development

Design and build reusable React components using functional components and hooks.

Utilize lifecycle methods (useEffect, useState, useContext, useReducer) effectively.

Build dynamic and accessible UIs using JSX and virtual DOM efficiently.

Manage state using local, lifted, and global state patterns (Redux, Context, Zustand, etc.).

Implement form validations and event handling using controlled and uncontrolled components.

Implement error boundaries and graceful error handling strategies.

Write unit and integration tests using Jest and React Testing Library.

Next.js Development

Architect and implement applications using App Router and various rendering strategies (SSR, SSG, ISR, CSR).

Develop custom pages using getStaticProps, getServerSideProps, and dynamic routing with useRouter.

Utilize layouts, nested routes, and parallel routes in the App directory.

Implement and maintain custom API routes (pages/api) for serverless functions.

Optimize performance via code splitting, dynamic imports, caching, and lazy loading.

Configure and maintain project settings in next.config.js and .env files.

Architecture & Patterns

Collaborate with product, backend, and DevOps teams to ensure end-to-end feature delivery.

Authentication & Security

Implement authentication flows using NextAuth.js, JWT, and token-based auth.

Protect routes and manage user sessions on client and server.

Apply best practices in security (CSRF protection, secure headers, safe storage).

API & Data Integration

Consume RESTful APIs and integrate with GraphQL using Apollo Client or React Query.

Handle data fetching, caching, pagination, and mutation with client- and server-side rendering in mind.

Integrate WebSockets for real-time capabilities.

Testing & Performance

Develop testable code with high unit test coverage.

Use tools like Jest, RTL, and Cypress (if applicable).

Conduct bundle analysis, memory leak prevention, and accessibility audits.

Optimize assets with next/image, next/font, and fine-tuned caching strategies.
