PROFILE

Steffen Grunwald

Contributed to the awslabs/cid-framework repository by developing a location-based carbon emissions export feature, enabling geography-specific reporting for more accurate carbon accounting. This work involved updating SQL queries to select new emission value and unit fields and modifying CloudFormation templates to support granular, location-driven data exports. Additionally, addressed a critical authorization issue in the aws-samples/aws-cudos-framework-deployment repository by updating IAM policies to grant athena:GetWorkGroup permission, ensuring error-free execution of custom SQL queries in Quick Suite. Leveraged Python, AWS CloudFormation, and IAM permissions management to deliver reliable, maintainable infrastructure changes that improved data export accuracy and operational stability.
