Worked on stackhpc/stackhpc-kayobe-config and stackhpc/ansible-slurm-appliance, focusing on infrastructure automation and security. Delivered features to improve build efficiency and access control by introducing zstd compression for IPA image builds and implementing a new baremetaluser role with updated OpenStack policies for controlled provisioning. Addressed a critical OpenSSL vulnerability in the Slurm appliance, updating dependencies and ensuring reproducible builds by correcting repository metadata and adding missing packages. Used Ansible, YAML, and cloud infrastructure skills to align platform governance with operational needs, demonstrating a disciplined approach to configuration management and security-focused development across both JSON and YAML-based workflows.
