Worked on the design and development of a high-performance, Fargate-based microservice for frequency management. This service is capable of handling an impressive 5 million transactions per second, thanks to the scalable architecture we've built leveraging various AWS services like SQS, DynamoDB, SNS, and more.In addition to the service development, I've also been responsible for setting up the entire AWS-based infrastructure, utilizing a cell-based approach and AWS CDK to ensure robust operations and maintainability. It's been an excellent opportunity to dive deep into the latest cloud technologies and architect resilient, large-scale systems.In the past, I have also worked on with the private marketplace team to re-architect their core services. This has involved establishing a new microservice to handle private marketplace deals, enhancing it with advanced analytics and troubleshooting capabilities to better serve our customers. I've also led the migration of the front-end from JSP to React, as well as transitioning the underlying database from CloudSearch to an internal solution.
