Worked on the TUM-DSE/doctor-cluster-config repository to deliver secure, auditable user management workflows for a university compute cluster. Developed end-to-end provisioning for student thesis access, automating SSH key management, group assignments, and home directory setup using Nix for reproducibility. Enhanced security by removing obsolete user accounts and associated SSH keys, aligning system configuration with onboarding and offboarding policies. Implemented onboarding automation for new developers, streamlining access and initial preferences. All changes were tracked through version control to ensure traceability and compliance. Demonstrated expertise in system administration, configuration management, and user management, focusing on operational efficiency and access governance.
