About

I’m currently working as a Software Engineer (SWE) at Google, where I’m part of the Google Play Store team, contributing to building scalable, reliable, and impactful systems that support billions of users worldwide. My role involves solving complex engineering challenges, optimizing large-scale distributed systems, and collaborating with talented engineers across products and platforms. Previously, I worked at Amazon as a Software Development Engineer, where I designed and developed scalable backend systems using Java, Spring Boot, and AWS Cloud Services for the BuyBack and Device Exchange platform across India and MENA. My work focused on building resilient microservices that powered high-impact customer experiences like Cart, Checkout, Payments, and Doorstep Delivery. Earlier, at Oracle, I worked as a Software Engineer, contributing to full-stack application development using Java, Spring Boot, Node.js, React.js, Redux, and MongoDB. I also led initiatives in UI optimization with Tailwind CSS and developed automation frameworks using Python, Cypress, and Postman, improving release cycles and ensuring high reliability. During my time at Oracle, I earned certifications in Oracle Cloud Infrastructure (OCI) and Data Management, and received the YES Award twice for delivering impactful, reliable solutions. 🎓 I hold a B.Tech in Computer Science Engineering from Heritage Institute of Technology and am passionate about system design, backend engineering, and building cloud-native applications that scale efficiently.
