About

As a System Engineer at TCS, I work on backend development for a healthcare client (Cigna), where I design and build scalable REST APIs using Java, Spring Boot, PostgreSQL, and microservices architecture. Working with real-world healthcare systems has strengthened my understanding of security, compliance (HIPAA), and reliability in large-scale applications. Before TCS, I worked as a Backend Developer Intern at ISDA, where I built EdTech platform features using Node.js, Express.js, MongoDB, and MySQL. I developed APIs for course enrollment workflows, student access management, and integrated secure authentication with JWT-based SSO, along with Razorpay payment gateway integration, improving API performance and overall user experience. Currently, I’m expanding my skillset into Machine Learning and AI, with the goal of combining backend engineering and intelligent systems to build smarter and scalable products. If you're working on something impactful—especially in backend engineering, AI-driven systems, or digital platforms—I’d love to connect and exchange ideas.
