Design, develop, and maintain scalable, high-performance full stack web applications using React 18.x/TypeScript and Node.js/NestJS services. Lead architecture discussions across reusable frontend component design, backend service boundaries, REST/OpenAPI contracts, AWS integration patterns, security, performance, accessibility, SEO, and observability. Architect and implement secure Node.js/NestJS REST APIs and AWS Lambda functions with validation, authentication/authorization, structured error handling, middleware, and Swagger/OpenAPI documentation. Build scalable DynamoDB/PostgreSQL data-access patterns (including indexing and query optimization) and event-driven workflows using AWS Lambda and Step Functions. Develop modular React applications using Hooks, Redux Toolkit/RTK Query, Context, and Micro Frontend patterns. Integrate headless CMS/AEM headless content and implement RAG/vector search workflows for enterprise retrieval needs. Containerize services with Docker and deploy via A

Developed scalable full stack modules using React 18.x/TypeScript and Node.js/NestJS with RESTful APIs and AWS services. Implemented Node.js/NestJS APIs and AWS Lambda functions integrated with React, including request validation, authentication/authorization, middleware, error handling, and Swagger/OpenAPI documentation. Built persistence using PostgreSQL/Prisma and Amazon DynamoDB, covering schema design, indexing, queries, and performance optimization. Implemented state-management strategies with Redux Toolkit, RTK Query/Context patterns, and Zustand for reusable React modules and micro frontend features. Created serverless workflows using AWS Step Functions and Lambda to coordinate asynchronous processing and integrations. Supported data processing with Amazon S3 and AWS Glue and analytical workloads in Amazon Redshift. Containerized services with Docker and supported deployments on Amazon ECS with CI/CD for repeatable releases. Implemented automated frontend and backend testing wi

Implemented client-side routing and navigation using React Router for SPA experiences. Built responsive, scalable React applications using React, JavaScript ES6+, TypeScript, HTML5, and CSS3/SCSS. Created reusable UI components with React Hooks and functional components, and managed complex client-side state with Redux/Redux Toolkit. Integrated RESTful APIs and handled asynchronous flows using Axios and Fetch. Developed Node.js/Express backend services and a Backend-for-Frontend layer to aggregate REST responses, apply business rules, validate requests, and simplify frontend integration. Migrated selected modules from Webpack to Vite to improve build performance. Built reusable, validated forms with user-friendly error handling. Improved performance and user experience with code splitting, lazy loading, memoization, and accessibility/SEO-aware development. Authored Jest tests and Storybook interaction tests; used JIRA/Confluence for requirements/defects and supported Jenkins CI/CD; mai
