In ESTech org we were involved in developing MyHR for amazon employees for better experience related to any problem they face. I was involved in design and development of an ECS Fargate service which was the core service interacting with Salesforce APIs. Later this service was getting utilised in deprecating Salesforce and moving to the in-house PXT-CMS solution.Currently working in TimeHub team where i designed and developed TimeClassification service responsible for defining TimeIntervals as per the configuration. This is one step towards deprecating MyTime(3rd Party) and move towards AmazonTime(In-house) goal.Also worked on deprecating TAAEventSystem which was built for vending out Punch, Schedule and TimeAway events to its consumers, I proposed and deprecated this entire solution by building the eventing mechanism on each of the domain owned infrastructure which reduced the cost and Operational load for the team.

Worked on UseTax project and delivered Phase-1 single handedly. This project saved $671K for Amazon. I was responsible in design and development of Phase-1. Later designed and developed an ECS service in Phase-II. The developed architecture used to process ~25-30Millions of transactions every month. I was working on Big Data technologies like EMR, Apache Spark, Scala etc.

Worked on reconciliation project Milaan which was responsible for matching ledgers. Implemented an EC2 service for the matching engine in Java which involved writing multiple APIs as per the usecase.
