During October 2025, Cruz developed comprehensive SSH tunnel documentation for Alps compute nodes in the eth-cscs/cscs-docs repository. Focusing on Markdown and documentation best practices, Cruz provided end-to-end guidance for developers, covering prerequisites, node allocation, server binding, and SSH tunnel command configuration. The documentation aimed to streamline onboarding and reduce time-to-access for engineers needing local service access via SSH tunneling. By standardizing workflows and clarifying technical steps, Cruz improved the accessibility of Alps services for new and existing users. The work demonstrated depth in documentation, a strong grasp of SSH concepts, and effective collaboration within a repository-driven development environment.
