About

As a Software Engineer at Walmart Global Tech India, I find joy in transforming complex challenges into innovative solutions. My journey began at the Birla Institute of Technology where I earned my BTech in Computer Science. Since then, I've been fortunate to work on exciting projects that push the boundaries of technology. One of my proudest moments was leading the migration of the Order Services application from WestUS to EastUS2. This wasn’t just about moving data; it was about enhancing performance while reducing costs significantly. By transitioning VMs and optimizing our Kafka and Cassandra setups, we achieved a remarkable 50% ramp-up in API traffic without compromising on efficiency. During my time as a Software Engineer II, I played a crucial role in upgrading our Solr cluster capacity. Handling over 78 billion records for Walmart Mexico’s 92 million customers was no small feat! The experience taught me the importance of meticulous planning and execution when dealing with such vast datasets—especially as we were growing by an astounding 240 million records each month. I also believe that monitoring is key to reliability. While interning at Walmart Global Tech, I developed dashboards for our Order Services and Order Management System (OMS). These tools not only helped track alerts but also ensured that our systems remained robust and responsive.
