Worked on the woocommerce/woocommerce repository, focusing on improving the reliability and maintainability of structured data handling in WooCommerce. Addressed a critical bug by ensuring the valueAddedTaxIncluded field is conditionally included in JSON-LD output only when taxes are enabled, which improved schema compliance and accuracy for stores with tax-disabled configurations. Enhanced code maintainability by updating the PHPStan baseline to reflect new conditional logic and aligning code style with PHPCS standards. Maintained CI stability by re-running tests after transient failures. Utilized PHP and back end development skills throughout, with a strong emphasis on data integrity and cross-team collaboration.
