 * Lead architecture and implementation of GraphQL services on our Apollo Federation supergraph
 * Build and improve Shopify integrations (Storefront API, Admin API, webhooks, order lifecycle) as part of a cross-team effort
 * Reconcile Shopify''s inventory-and-SKU commerce model with our made-to-order, print-on-demand fulfillment flow, where the order lifecycle is the hard problem
 * Define and improve service boundaries, data models, and integration points across systems
 * Partner with frontend, product, and platform teams to simplify how teams build and integrate
 * Diagnose and resolve deep distributed-systems and runtime-level failures, including federation transport behavior, connection-pool issues, and event-loop performance under load
