About

At Amazon, I contribute to the development of scalable internal tools and automation processes for the Amazon Appstore ecosystem. My role as an Application Engineer focuses on designing, building, and deploying Java-based backend systems with an emphasis on performance, reliability, and maintainability. Previously, at Tata Consultancy Services, I worked on BFSI projects for SBI General Insurance, enhancing system scalability and responsiveness. My efforts included developing Java-based microservices, creating REST APIs, and implementing event-driven architectures with Apache Kafka. A graduate of Heritage Institute of Technology in Electronics and Communication Engineering, I am skilled in AWS Lambda, Claude Agent SDK, and Anthropic Claude.
