About

Currently pursuing a Full-Time MBA at Imperial College Business School, I hold a B.Tech in Computer Science from Delhi Technological University and bring 5+ years of experience in backend development and digital product innovation at Freecharge Payment Technologies (subsidiary of Axis Bank) and Info Edge India Ltd. I have a proven track record of leading complex projects, optimizing APIs, and migrating legacy systems to modern architectures using technologies such as Java, Spring, MySQL, MongoDB, Kafka, Aerospike, and AWS. My work has been recognized with multiple awards, including two GOLD Awards at the Info Edge Merit Awards and several Rockstar Awards. Beyond my technical expertise, I am passionate about giving back to the community. As a member of the Om Foundation and the Magadh Mission Foundation, I have organized events and workshops to improve the lives of underprivileged children. Outside of work, I am an avid traveler with international travel experience, always eager to explore new places and cultures.
