Worked on the Shopify/polaris repository to deliver a comprehensive Global Privacy Control (GPC) integration, focusing on privacy-first user experiences. Leveraged React and TypeScript to implement end-to-end GPC coverage across both client and server, ensuring that Google Tag Manager is only loaded when user consent is granted. Upgraded dependencies, including @shopify/dux to version 5.0.1, to support GPC compliance and updated server loaders and partials for accurate privacy signal detection. Enhanced the test suite to align with the latest privacy signal API, and provided local validation guidance and demos, reinforcing regulatory compliance and strengthening the platform’s data privacy posture.
