About

As a Sr. Software Engineer at Paytm, one of India's leading digital payment platforms, I develop scalable, reliable, and secure microservices and serverless applications that serve millions of users and transactions daily. I have a B.E in Computer Science from Chitkara University and a passion for using cutting-edge technologies such as AWS, Java, Spring Boot, and gRPC. I work on the payment core and biz service, a microservice that performs core operations of payments, enabling various pay modes and deploying on Kubernetes. I also work on the refund decision service, a service that executes rules by a rule engine and decides the customer's refunds to the selected destination, using Akka framework and non-blocking functionality. Previously, I worked at Evive, where I facilitated tag-based user categorization, updated the architecture to follow a unitive and extensible design, and contributed to the security and performance of the APIs. I have multiple certifications in problem-solving and Spring Boot, and strong skills in Amazon Aurora, Amazon Kinesis, and Spring Webflux.
