React Frontend Development(Primary Focus)

•Architect, build, and maintain complex Reactapplications — dashboards, analytics platforms, internal tools, andcustomer-facing products

•Develop responsive, mobile-first UIs optimized fortablet (iPad) and desktop with pixel-perfect execution

•Build rich data visualizations using D3.js, Recharts,Chart.js, or custom SVG/Canvas components

•Implement advanced state management patterns usingRedux Toolkit, Zustand, React Query, or Context API

•Create reusable, well-documented component librarieswith design system integration (Tailwind CSS, Styled Components, or CSSModules)

•Optimize frontend performance: code splitting, lazyloading, memoisation, virtual scrolling, bundle analysis

•Write comprehensive tests using Jest, React TestingLibrary, and Cypress for E2E testing

•Implement real-time features using WebSockets,Server-Sent Events, or polling strategies

API Design & BackendDevelopment

•Design and build RESTful APIs using Node.js(Express/Fastify) or Python (FastAPI/Flask) following OpenAPI specifications

•Develop GraphQL APIs where appropriate for complex dataquerying 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)

•Implement API versioning, pagination, filtering, andsearch capabilities

•Build and maintain microservices or serverlessfunctions (Azure Functions / AWS Lambda)

•Create API documentation using Swagger/OpenAPI andmaintain developer-facing docs

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 datasetsand serve them through optimized APIs

•Implement caching strategies (Redis, CDN, browsercache) for high-performance data delivery

•Connect to third-party services and APIs (paymentgateways, CRM, loyalty platforms, analytics tools)

AI / LLM Integration

•Build conversational AI interfaces (chatbots, knowledgeagents) using LLM APIs (OpenAI, Anthropic, Azure OpenAI)

•Implement RAG (Retrieval-Augmented Generation) patternsfor document Q&A; and contextual search

•Create prompt engineering frameworks and manage AIresponse 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 toKubernetes or cloud-managed services

•Implement monitoring, alerting, and observability(Datadog, Recent Relic, or Application Insights)

•Conduct code reviews, mentor junior developers, anddrive engineering best practices
