Working as a full-stack developer on the “Buy With Prime” product offered by Amazon for the “Direct To Customer” platforms, creating and maintaining micro-services.
I owned end to end design and implementation of micro-services, primarily in java based business logic and AWS infrastructure setup using AWS CDK in typescript, keeping up with IAC ( infrastructure as code ) best practices.
Having code contributions in over a dozen microservices, I got exposure to Kotlin and Scala alongside with java implementing accessor and observer design patterns and utilizing global libraries like MapStruct and Apache while creating internal libraries for wider code usage.
Worked on “Ruby on Rails” based front end to migrate from default shopper experience to “Buy with Prime” specific shopper experience on APay and worked on React based front end to resolve shopper facing issues and improving the accessibility of the website for all shoppers.
I improved team processes by owning meetings like backlog grooming and connections review leading to a better work environment for the team and was an active contributor for the team as a code reviewer.
I setup org wide guidelines for Integration Test Code Coverage using an AWS tool Cloud-Cover and helped remove code smells like dead and uncovered code.
