• Build and deploy custom platform extensions using Shopify Functions, Checkout UI Extensions, Customer Account UI Extensions, and Shopify Admin extensions
• Develop robust backend services, webhook consumers, and data synchronization pipelines integrating Shopify with third-party enterprise systems (ERP, PIM, OMS, CRM)
• Partner with the Shopify Solution Architect to break down high-level system designs into actionable engineering tasks, technical specifications, and sprint deliverables

• Drive storefront and API performance optimization—managing edge caching strategies on Shopify Oxygen, optimizing GraphQL query costs, and ensuring green Core Web Vitals
• Champion the adoption of AI-native development workflows across the team (e.g., Claude Code, Cursor, GitHub Copilot) to accelerate feature delivery, scaffolding, and complex refactoring
