• As part of the architecture team, responsible for creating and communicating standards with regards to best practices for implementing and deploying software running on EC2, Lambda, and Docker/ECS/Fargate. • Led the migration of .Net Core micro services from EC2 to Docker/Fargate to scale more granularly and increase reliability. • Wrote C# and Python Lambda functions which used AWS Simple Notification System (SNS), Simple Queue Service (SQS), Simple Storage System (S3), Step Functions and CloudWatch logs to import and transform data loaded from various medical provider data sources into Redshift and Aurora databases which were integrated into the Phynd website and API services. • Implemented auto scaling based on SQS metrics to process Aurora (MySql) and ElasticSearch data using EC2 instances running C# (.Net Framework 4.6.1+) Windows services. • Designed continuous integration and deployment process using CloudFormation, CodePipeline, CodeBuild, CodeDeploy and later OctopusDeploy across multiple AWS accounts (DEV/QA/Stage/UAT/Production). • Developed C#/ASP.Net Core REST APIs hosted on both Lambda with API Gateway and Docker/Fargate used by both internal products and customer’s websites and mobile applications. • Deployed highly available third-party web applications using autoscaling, route 53, Application Load Balancers, Amazon Certificate Manager and http based health checks. • Designed and developed a document management system using JavaScript Node/Express that allowed users to upload and download documents from the website and allowed clients to integrate document retrieval with their website and mobile applications. The API was deployed as a Docker container on AWS Fargate behind a separate Nginx container. It also resized uploaded images asynchronously via a Python lambda function.
