Worked on the TUM-DSE/doctor-cluster-config repository to deliver secure, auditable user and reviewer access management over a three-month period. Focused on SSH key provisioning, access control updates, and reviewer onboarding, the work leveraged Nix and Nix scripting to automate configuration management and streamline privilege changes. Implemented targeted SSH key updates and group membership adjustments to reflect evolving user roles, while also adding and maintaining reviewer configurations for the ASPLOS review process. Emphasized traceability and compliance by ensuring all changes were clearly documented in version control, reducing manual overhead and supporting efficient, secure onboarding and collaboration across academic and reviewer teams.
