Worked on the gardener/gardener-extension-provider-openstack repository to deliver a security hardening feature for the Gardener OpenStack extension provider. Focused on enhancing deployment security by introducing PSS restricted compliance attributes, including seccomp profiles and capabilities management, to enforce reduced-privilege execution and align with security best practices. Updated internal Helm charts with securityContext configurations and automated the propagation of these changes using make generate, ensuring consistent and compliant deployments. This work supported ongoing compliance and governance initiatives, improving audit readiness for OpenStack environments. Utilized skills in Cloud Infrastructure, DevOps, and Kubernetes, with YAML as the primary language for configuration management.
