At Cognizant Technology Solutions, I worked on a full-stack retail application using Java, Spring Boot, and React, focusing on backend services and API development.
I contributed to RESTful API design and modular backend services following microservices principles. I also participated in database design and explored caching techniques to improve application performance.
For my Network Inventory & Health Check System project, I developed a platform using React, Spring Boot, and Tailwind CSS with automated device health monitoring. I implemented JWT-based authentication and role-aware API access control, and integrated MySQL for device inventory and health records.
I also built a real-time chat application with WebSockets and STOMP, and a cab booking application using React, Node.js, Express.js, and MongoDB. Both projects included JWT authentication and REST APIs; the cab booking project also integrated a payment gateway.
