Senior full stack developer building scalable enterprise web apps with Angular, Node, and REST APIs.
IndiaWhat I'm looking for
I’m a Senior Full Stack Developer with 5+ years of experience building scalable enterprise web applications across Healthcare and Analytics. I focus on API-driven workflows, responsive UI development, and dependable backend integrations.
At Tata Consultancy Services, I developed enterprise reporting applications with Angular, TypeScript, JavaScript, Node.js, Express.js, and MongoDB. I optimized frontend data handling and API workflows, reducing payload size by 40% and improving responsiveness.
I’ve also driven measurable performance gains through state management and visualization improvements. With Angular Signals, RxJS, and NgRx, I reduced unnecessary rendering cycles, and with Highcharts plus backend image generation, I lowered chart insertion time from ~10 seconds to under 3 seconds.
Previously at Cognizant Technology Solutions, I built secure healthcare portal modules, integrating OAuth 2.0 and JWT-based authentication, and supporting Federated Single Sign-On (FSSO) for 200,000+ users. I enjoy Agile delivery, production support, automated testing, and using tools like GitHub Copilot to accelerate refactoring, documentation, and testing.
