About

As an SDE-2 at Adda247, I focus on developing scalable backend solutions to enhance user engagement and platform efficiency. My contributions include leading teams to create a short-video learning platform, building low-latency home feed infrastructure, and deploying a global content search system using ElasticSearch, which improved content discoverability and reduced query response times. Holding a BTech in Computer Science from the College of Engineering Roorkee, I bring expertise in leadership, Java, Redis, ElasticSearch, Apache Kafka, and software infrastructure. I am motivated by opportunities to optimize processes, mentor teams, and develop impactful systems that drive business growth and user satisfaction.
