Jean-Philippe Pellerin developed a DUX-based cookie consent and Google Tag Manager (GTM) integration for the Shopify/polaris repository, focusing on regional cookie policy compliance and centralized consent management. He delivered a DUX CDN version for polaris.shopify.com, enabling unified privacy controls and reducing maintenance overhead. The solution migrated GTM functionality to DUX, allowing for consistent consent gating and improved privacy compliance reporting across regions. Utilizing JavaScript, TypeScript, and React, Jean-Philippe’s work addressed the need for scalable, maintainable web privacy infrastructure. The project demonstrated depth in front end development and web compliance, though it was limited in scope to a single feature.
