• Build rich data visualizations using D3.js, Recharts, Chart.js, or custom SVG/Canvas components
• Implement advanced state management patterns using Redux Toolkit, Zustand, React Query, or Context API
• Create reusable, well-documented component libraries with design system integration (Tailwind CSS, Styled Components, or CSS Modules)
• Optimize frontend performance: code splitting, lazy loading, memoisation, virtual scrolling, bundle analysis
• Write comprehensive tests using Jest, React Testing Library, and Cypress for E2E testing
• Design and build RESTful APIs using Node.js (Express/Fastify) or Python (FastAPI/Flask) following OpenAPI specifications
• Develop GraphQL APIs where appropriate for complex data querying needs
• Implement authentication and authorization (OAuth 2.0, JWT, RBAC) for secure API access
• Build middleware for logging, rate limiting, caching, error handling, and request validation
• Design database schemas and write efficient queries (PostgreSQL, MongoDB, or similar)

Integration & Data Layer

• Integrate frontend applications with data platforms (Databricks, data warehouses, data lakes) through API layers
• Build data ingestion endpoints that accept, validate, transform, and store incoming data
• Work with data engineers to consume curated datasets and serve them through optimized APIs
• Connect to third-party services and APIs (payment gateways, CRM, loyalty platforms, analytics tools)

AI / LLM Integration

• Build conversational AI interfaces (chatbots, knowledge agents) using LLM APIs (OpenAI, Anthropic, Azure OpenAI)
• Implement RAG (Retrieval-Augmented Generation) patterns for document Q&A and contextual search
• Create prompt engineering frameworks and manage AI response streaming in React UIs

DevOps & Delivery

• Set up and maintain CI/CD pipelines (GitHub Actions, Azure DevOps, GitLab CI)
• Containerize applications with Docker and deploy to Kubernetes or cloud-managed services
• Implement monitoring, alerting, and observability (Datadog, New Relic, or Application Insights)

Requirements
