• Responsibilities: Identify, design and improve the platform, handle client day to day feature requests, support within team and away team projects and also improve the team's operational and engineering overhead
• Regression and load testing framework re-architecture:
• Designed, developed and re-architected existing monolithic architecture system onto a micro-service based architecture using AWS Step functions, ECS Fargate and Lambdas and introduced on demand resource provisioning and scaling capability, fine grained TPS control, separation of compute logic to allow the framework to evolve and be re-used. This has also reduced our infrastructure cost by 30\% and prevented noisy neighbour problem in our platform.
• Generic bundling cataloguing, lifecycle and bundle level notification service:
• Designed and developed end to end generic bundling capability supporting bundling multiple digital and physical products together from cataloguing , staging to downstream publishing of product, image and price metadata including CRUD lifecycle management. Also, have built a bundle level notification service to generate notifications for any entity or relationship changes for any bundle or it's component to help our dependent teams to re compute bundle level information they persist. This allowed Amazon to up-sell digital subscriptions together and along with physical products as well.
• Supported multiple away team projects:
• Designed, co-authored and supported development testing and deployment of multiple changes required for various teams on our platform like bundling marketplace expansion, amazon appstore metadata localisation, amazon appstore privacy labels project, vending api support for bundles, kindle readability experience improvement

• Responsibilities: Design and improve the platform, handle client day to day feature requests and also improve the team's operational overhead
• Ultra fast feed publishing service:
• Designed and implemented core publishing framework for our team using asynchronous generic step based workflow service, feed store and publishing status tracking store. Integrated this new core service with all of our existing core feed generation services and replaced 600+ distributed time based batch jobs and drastically reduced corresponding operational load for maintenance
• Generic attribute fanout mechanism:
• Designed and developed a self serviceable attribute fanout mechanism that is used to propagate offer related attributes from parent series to child ebooks and this allowed Amazon to launch Wait For Free program in Japan which increased profit by almost 30\% for both Amazon and publishers}
• Operational Excellence Improvements:
• I've significantly worked on making sure that the service and infra-hygiene are maintained by making sure mandatory software and patch upgrades are done and also infrastructure costs are optimised by implementing TTL, removing unwanted resources/descaling. Also, identified internal tools to generate operational dashboards, used AI based ticket summarizer tool to identify common patterns and fix the root problem

• Responsibilities: Work on isolated projects improving the platform and also improve the team's operational overhead
• Java sandbox:
• Designed and developed an in code logic replacement online code editor tool which utilizes in memory java compilation to override existing logic for a single request that is used by our team developers and our tenant teams to try out their business logic updates without actually doing the code change in our code base.
• Improved performance of team's code:
• Setup warm-up queries for all regions of our service to keep latency settled , also updated our service logic to use parallelisation for downstream calls and did some dependency graph cleanup, setup code pipelines, metric dashboards and did mandatory upgrades
