Worked on the Ecwid/ecwid-java-api-client repository to deliver Tax Class Code support within order processing and calculations. Introduced a new taxClassCode field to order data structures, enabling accurate tax class tracking even when catalog data changes, such as product deletions. Applied immutability safeguards in the UpdatedOrder model to prevent accidental modifications and handled nullable taxClassCode values to maintain calculation accuracy. Expanded test coverage to ensure resilience in scenarios where catalog state impacts tax calculations. Utilized Kotlin for backend and API client development, focusing on robust data modeling, code formatting, and comprehensive testing to enhance order calculation fidelity and reliability.
June 2025 monthly summary for Ecwid/ecwid-java-api-client: Delivered Tax Class Code (taxClassCode) support across order processing and calculations, introducing a new field on order data structures, enacting immutability safeguards in UpdatedOrder to prevent accidental changes, and handling nullable taxClassCode to preserve accuracy when catalog data changes. Expanded test coverage to cover nullable values and new calculation paths, ensuring resilience when catalog state changes (e.g., deletions) impact tax calculations. Implemented protective behavior where tax is reset to a standard rate if a product is deleted from the catalog, preventing stale or incorrect tax calculations.
