In this project, I use AWS CDK to build CI/CD pipelines for a client to accomplish automated testing and automated deployment to AWS S3 and AWS ECS. Furthermore, I develop an AWS lambda function using AWS DynamoDB to make the client's AWS resources scale up and scale down automatically to save cost.
