Hengyue Wu contributed to the isomerpages/singapore-customs-cms repository by developing and maintaining regulatory content publication workflows and documentation updates. Over the month, Hengyue published new regulatory PDFs and notices, ensuring that public directories reflected the latest customs circulars and Free Trade Zones regime changes. Using Markdown for structured documentation and applying content management best practices, Hengyue systematically removed outdated materials and maintained consistent file naming for improved discoverability. The work focused on keeping regulatory information accurate and accessible, with disciplined documentation cleanup and governance. This approach demonstrated depth in content lifecycle management and technical rigor in documentation processes.
