Aleksandra Swierkowska developed user provisioning and access control functionality for the TUM-DSE/doctor-cluster-config repository, focusing on secure onboarding and governance. She configured the system to add two new users, assigning SSH keys, group memberships, and shell restrictions to ensure compliance with access policies. Using Nix for configuration management, she emphasized version-controlled traceability and reduced manual intervention in user management. Her work streamlined the process of granting access while maintaining auditability and security. Although the scope was limited to a single feature over one month, the implementation demonstrated solid skills in system administration, user management, and infrastructure-as-code best practices.
