In March 2026, Mwhg Voets developed a concurrency-enabled destruction workflow for the aws/aws-cdk-cli repository, introducing a --concurrency flag to the cdk destroy command. This feature allowed multiple AWS CloudFormation stacks to be destroyed in parallel while maintaining correct dependency order. Voets implemented a WorkGraph-based orchestration using reversed dependency edges, isolating graph construction logic in a dedicated module and coordinating stack execution through a focused process. Working primarily with TypeScript and leveraging AWS CDK and CLI development skills, Voets addressed a longstanding performance issue, delivering a robust solution that improved operational efficiency for teams managing complex infrastructure projects.
