Jordi focused on improving documentation for container image signing practices across the EnterpriseDB/cloudnative-pg and cloudnative-pg/postgres-containers repositories. He updated Markdown-based guides to clarify that only 'minimal' and 'standard' images are signed using cosign, while explicitly noting the deprecation of unsigned 'System' images. By architecting consistent documentation across both repositories, Jordi helped users and operators better understand which images are trusted, reducing the risk of misconfiguration and supporting a stronger security posture. His work emphasized clear, actionable guidance and set a foundation for broader compliance, demonstrating depth in technical writing and a strong grasp of container security concepts.
