PROFILE
Daniel O'sullivan
Daniel O’Sullivan focused on stabilizing end-to-end test reliability for the tloncorp/tlon-apps repository by addressing SELinux-related permission issues in Podman-based CI environments. He engineered a solution that configured SELinux relabeling on volume mounts and disabled SELinux labels for Podman containers, enabling parallel test execution without security-induced failures. Working primarily with Shell scripting and leveraging his expertise in CI/CD and DevOps, Daniel’s changes reduced flaky test runs and improved feedback speed for feature development. His work demonstrated a strong understanding of Linux security and containerization, resulting in a more robust, security-conscious testing workflow compatible with SELinux-enabled systems.
