Worked on the Shopify/polaris repository to deliver a DUX-based cookie consent and Google Tag Manager (GTM) integration, focusing on regional cookie policy compliance and centralized consent management. Developed and deployed a DUX CDN version for polaris.shopify.com, enabling unified gating of cookies and streamlined privacy controls across regions. Migrated existing GTM functionality to DUX, reducing maintenance overhead and improving compliance reporting. Utilized JavaScript, TypeScript, and React to implement these front end solutions, ensuring that cookie consent management is both robust and adaptable to varying regulatory requirements. The work addressed privacy needs while enhancing maintainability and scalability for future development.
