Mitch Alessio contributed to the CMSgov/beneficiary-fhir-data repository by developing infrastructure and automation for performance testing, configuration management, and data pipeline processing. He implemented a Locust-based performance testing service using AWS Lambda, Athena, and Glue, enabling automated feedback and analytics on system performance. Mitch also built a configuration service leveraging AWS SSM Parameter Store and Terraform, improving environment configuration integrity through SOPS validation. In addition, he delivered a scalable CCW manifest processing pipeline using AWS ECS/Fargate, Lambda, and CI/CD automation. His work demonstrated depth in Python, Terraform, and AWS services, focusing on reliability, automation, and maintainability.
