Software Development Engineer III building scalable, high-availability backend services and GenAI automation for Expedia Group.
IndiaWhat I'm looking for
I’m a Software Development Engineer focused on designing and shipping large-scale backend systems that stay reliable under real-world load. At Expedia Group, I led architecture and development of cross-brand Trip Item Details backend services, supporting 40M+ users annually and cutting customer support contact rate by 18%.
I also own critical product modules end-to-end, including Booking Summary, enabling travelers to self-serve stay details and increasing self-service usage by 25%. I’ve modernized microservices with Kotlin, gRPC, and Spring Boot on AWS (reducing API latency by 40%), optimized Kafka-based systems (30% faster event processing), and built a GenAI automation framework that generated GraphQL schemas and mock Kotlin responses—cutting development time by 95% across multiple teams.
