PROFILE
Doug Goldstein
Worked on the rackerlabs/understack repository to modernize and stabilize core data services, focusing on cloud-native environments. Upgraded messaging and database dependencies using Helm and Kubernetes, improving reliability and maintainability while reducing operational overhead. Standardized the codebase for Python 3.12 compatibility and enhanced deployment workflows by integrating the latest Ironic features and reverting changes that caused SSL issues during provisioning. Led targeted cleanup by retiring legacy AppSets, simplifying the deployment pipeline and aligning with modernization goals. Demonstrated expertise in Ansible, Python, and CI/CD, consistently delivering features and fixes that improved deployment safety, maintainability, and future readiness of the platform.
