Worked on the woocommerce/woocommerce repository, focusing on backend development and testing to address a targeted bug affecting regional data consistency. Using JavaScript and PHP, implemented a precise fix to standardize the formatting of the Kurdistan state name, ensuring it matched conventions used for other states. Updated related test data and API tests to reflect the corrected naming, preventing future regressions and supporting reliable merchant data handling. Coordinated changes across code, tests, and release artifacts, including documentation in the changelog, to maintain cross-file consistency. The work emphasized careful attention to detail and thorough validation within the API development and testing process.
