I’m a Programmer Analyst Trainee focused on building scalable RESTful services and clean, user-friendly interfaces. I architect and deliver enterprise-ready APIs while keeping design disciplined through SOLID principles.

At Cognizant Technology Solutions, I’ve worked on end-to-end application lifecycles—using Git for version control and Postman for comprehensive API testing to support seamless deployment readiness. I also integrate React.js frontend components with secure backend services via Axios to deliver responsive, dynamic UI experiences with reduced rendering latency.

Earlier, as a Software Developer Intern at Edutitan Venture Private Limited, I engineered server-side architecture with Node.js and Express.js, implementing secure REST endpoints and robust user data management. I designed MongoDB schema models for efficient indexing, storage, and fast query retrieval, and I built a fully responsive frontend with cross-browser compatibility.

My project work reflects my full-stack mindset: KaamKaaj uses Spring Boot and React with multi-tenant workspace isolation, JWT authentication with refresh token rotation, and a granular RBAC engine using custom SpEL. DocVault adds secure document storage with AWS S3 and deploys a backend on AWS EC2, while NomadCabs delivers real-time cab booking using Java Spring Boot, React, and MySQL-backed REST APIs.
