Over a two-month period, contributed to SalesforceCommerceCloud’s commerce-sdk-isomorphic and pwa-kit repositories by focusing on API stability and dependency modernization. In commerce-sdk-isomorphic, refactored API definitions by migrating enums to type unions and relaxing query parameter typing using TypeScript, which reduced runtime errors and improved maintainability. This approach enhanced type safety and flexibility for future API changes. In pwa-kit, upgraded the commerce-sdk-react dependency and synchronized it with commerce-sdk-isomorphic v3.4.0, ensuring compatibility and preparing the system for future enhancements. Work centered on API development, code generation, and full stack development using JavaScript, TypeScript, and Mustache templates.
