Full‑stack developer focused on React, Node.js and scalable web applications.
I am a full‑stack developer with hands‑on experience building scalable web applications using React.js, Node.js and MongoDB. I take pride in producing performant user interfaces and secure backend APIs that power real‑world features.
During an SDE internship I implemented Redux Toolkit for global state management, created JWT‑secured REST APIs, and integrated MongoDB for efficient session and user management. My work reduced redundant API calls by 30% and improved load times by 15%.
I've built end‑to‑end projects including a high‑performance Netflix clone with Firebase authentication and a real‑time networking platform using Socket.io, JWT and bcrypt. I focus on responsive design, low‑latency real‑time features, and robust security practices.
I hold a B.Tech in Computer Science and Engineering and continuously expand my skills through certificates in Data Structures & Algorithms, JavaScript and Node.js. I seek to join teams that value clean engineering, measurable impact, and collaborative problem solving.
