Product Manager & Developer
Zia ur Rehman leads product and engineering at Apimio, the Shopify-native catalog operations platform. He works hands-on across the product — the Variant Manager for complex catalogs, the Quality Guard publish gate, GraphQL Admin and Bulk Operations integrations, Shopify Markets localization, and the webhook-driven multi-store sync Apimio’s customers run on.
His experience sits in the PIM and ecommerce space: years spent close to how online merchants actually manage product data — importing messy supplier feeds, keeping multiple storefronts in sync, and publishing complete, accurate listings at scale. On apimio.com he writes the technical, no-fluff guides, turning real Shopify operator problems (“we edited a product in store A and forgot store B”) into concrete, implementable solutions.
