• o Developed a feature to display the status of republish jobs started by clients to republish the events in a pub-sub service that we own. Clients can now see the complete history of all the republish jobs triggered in the past on the pipeline owned by them.
• o Orchestrated canary deployments of lambda functions for seamless updates, ensuring minimal disruption to operations. Implemented error handling for deployment resilience using Cloudwatch and Splunk alerts.
• o Proposed circuit breaker approach to safeguard against booking loss during suspend-resume flow.
• o Investigated global Aurora database for database synchronization in multi-region ODS service to prevent booking impact.
• o Implemented crucial enhancements in the loyalty program, such as introducing variable expiry for reward points, resulting in significant cost savings for Expedia by preventing indefinite rewards availability.
• o Implemented coupon generation upon platinum upgrade, incentivising clients to utilize more points for upgrades and receive additional coupons, thereby enhancing customer engagement and loyalty.
• o Contributed to end-to-end testing for the multi-currency feature, enabling clients to seamlessly utilize loyalty points across different countries, thereby enhancing accessibility and user experience in diverse currencies.
• Tech Stack: AWS, Spring Boot, Apache Kafka, Java8

• o Contributed in development of various modules of TransactionBridge Service which facilitates the seamless exchange of events between clients by receiving incoming events on http endpoint or s3 bucket and distributing them to various clients through multiple delivery channels, utilizing HTTP, S3, and Kafka protocols to deliver events to different clients according to their specific requirements and preferences. Also worked on event retires, event republish, circuit breaker functionalities to make the system resilient.
• o Led the design and implementation of a generic Kafka consumer, enabling efficient event consumption from Kafka streams to drive real-time data processing and analytics. Designed a flexible solution for a generic kafka consumer service allowing clients to specify the number of consumers and configurations on-the-fly and streamlined setup and management of Kafka consumers for diverse topics.
• o Developed an OAuth token caching solution, significantly reducing the load on client systems. Authored High-Level Design (HLD) and Low-Level Design (LLD) documents to outline the architecture and implementation details.
• Tech Stack: AWS, Spring Boot, Apache Kafka, Java8
