About

I’m a final-year Computer Science (AI) student at Chitkara University with a strong focus on backend engineering and applied AI. I enjoy building systems that are structured, scalable, and reliable. My foundation in Data Structures and Algorithms helps me design efficient logic, while my experience with Node.js, Express, MongoDB, SQL, and REST APIs allows me to turn that logic into production-ready applications. Through freelance work and my internship experience, I’ve contributed to backend feature development, API integration, debugging, and database design. In projects like DriveGuard and GoHealthy, I focused on clean architecture, authentication handling, and maintainable backend structure. Alongside backend development, I have worked with Machine Learning and NLP concepts and understand how data-driven systems are built and deployed. I believe strong fundamentals matter. Clean code, structured thinking, and ownership over tasks define how I work. I’m currently seeking Software Engineer Intern, Entry-Level Backend Developer, or AI/ML roles where I can contribute to real-world systems and continue sharpening my engineering depth. If you’re building scalable products and value fundamentals, I’d be glad to connect.
