Hari Natarajan

I've built healthcare and e-commerce web applications at Tech Mahindra (Vision Quest Solutions), including MediCare Plus and ShopSphere. I contribute across the SDLC, from requirement analysis through deployment and production support.

For MediCare Plus, I developed patient registration, appointment scheduling, medical records, prescriptions, billing dashboards, and secure FastAPI services. I integrated REST and GraphQL APIs, implemented role-based access control, and optimized PostgreSQL data workflows.

For ShopSphere, I built product catalog, cart, checkout, and order-tracking experiences using React.js, Next.js, TypeScript, Redux Toolkit, and FastAPI. I improve reliability with Jest, React Testing Library, and Cypress, and support deployments using Docker, AWS, GitHub, and CI/CD pipelines.
