Lim Pei Zhen developed publishing enhancements for the Singapore Customs CMS, focusing on the isomerpages/singapore-customs-cms repository. She implemented a metadata-driven workflow for media releases, enabling static site publishing by integrating PDF asset support and structured metadata using Markdown. Her work included creating the Singapore Customs Media Release Page and establishing asset naming conventions to streamline future releases. Emphasizing content management and documentation, Lim ensured reliable asset delivery and improved publish readiness for timely media distribution. While the scope was limited to one feature over a month, the changes addressed workflow efficiency and traceability without introducing or resolving any bugs.
