Atul Kumar

​I am a Full-Stack Product Developer specializing in building cohesive web and mobile ecosystems from the ground up. With deep expertise in the MERN stack, PostgreSQL, and React Native, I don't just build apps—I launch businesses. My most recent success is Klassin.co.in, where I architected, developed, and deployed the entire web and mobile infrastructure single-handedly. Whether you need a high-performance web platform or a cross-platform mobile app, I provide the end-to-end technical leadership required to turn complex ideas into scalable, production-ready reality.
