In January 2026, Madsid developed conditional IAM Roles support for AWS SAM Functions in the aws/serverless-application-model repository. By leveraging AWS::NoValue within CloudFormation templates, Madsid enabled roles to be created only when necessary, optimizing resource usage and reducing potential costs. The implementation introduced new role resolution methods to handle conditional assignments, minimizing the permission surface and improving deployment flexibility. Madsid wrote extensive unit tests in Python to ensure correctness and reliability across various scenarios. This work enhanced security posture and provided customers with more adaptable deployment options, demonstrating a deep understanding of AWS SAM, CloudFormation, and automated testing practices.
