Chenghao Chen developed three backend features for the facebook/facebook-for-woocommerce repository over a three-month period, focusing on enhancing event tracking and attribution for WooCommerce merchants. He implemented referrer tracking by capturing and sanitizing HTTP_REFERER data within event objects, improving campaign measurement and privacy. Chen integrated the Facebook CAPI Parameter Builder library, extending both client-side JavaScript and server-side PHP tracking to increase fbc and fbp parameter coverage and address missing values in initial events. His work demonstrated depth in API integration, plugin development, and backend engineering, resulting in more reliable conversion tracking and data-driven marketing capabilities for the plugin.
