Worked on deployment reliability and infrastructure security across two repositories, focusing on production and staging environments. For pulibrary/orangelight, updated deployment configuration to include the catalog5 server in production, streamlining release processes and reducing manual intervention. In pulibrary/princeton_ansible, implemented IP-based access restrictions and security logging for the lockers and study spaces staging environment, introducing a reusable Nginx configuration template to enforce Princeton-only access. Collaborated cross-team to enhance security governance and auditability. Leveraged skills in DevOps, configuration management, and infrastructure security, using Ruby and Nginx to deliver targeted improvements that address operational gaps and strengthen environment controls.
