Worked on expanding the ProductType enumeration in the palantir/sls-packaging repository by introducing a new MODULE_V1 constant, enabling the system to recognize and categorize a new product type. The implementation included defining the enum in Java and mapping it to a corresponding JSON property, ensuring accurate serialization and deserialization within packaging workflows. This change improved automation and reduced the need for manual configuration, while maintaining backward compatibility for existing integrations. The work demonstrated disciplined change management and a focus on API and JSON alignment, leveraging skills in enum definition and Java to support evolving packaging requirements without introducing regressions.
