PROFILE
Sönke Liebau
Worked on Kubernetes operators within the Stackable ecosystem, delivering features and fixes across repositories such as stackabletech/trino-operator and stackabletech/secret-operator. Focused on enabling multi-tenant deployments by introducing distinct ServiceAccounts per Stacklet, upgrading dependencies, and refining RBAC resource management using Rust and YAML. Enhanced reliability by improving error handling with Snafu and updating documentation for Active Directory integration and Helm chart parameters. Addressed configuration correctness in Kubernetes environments by clarifying kubelet work directory usage and aligning Helm parameters, reducing misconfiguration risk. Maintained clear changelogs and inline documentation to support maintainability and onboarding for future contributors and users.
