Worked on the TUM-DSE/doctor-cluster-config repository to automate secure onboarding for new students in a cluster environment. Developed and scripted user provisioning features using Nix, focusing on per-user configuration, SSH key management, and system administration. Each feature enabled the creation of new system users with dedicated home directories, login shells, unique identifiers, and access controls, ensuring secure and auditable access for students. Leveraged Git-based version control to maintain traceability and reproducibility of configuration changes. The work streamlined the onboarding process, reduced manual intervention, and strengthened access security, demonstrating proficiency in DevOps practices, Nix scripting, and user management workflows.
