Shopify app and storefront development
Custom Shopify apps with billing and OAuth, headless storefronts on Hydrogen, theme work where it earns its place. Built around the merchant operator, not the agency invoice.
Looking for a Shopify app developer, a Shopify Hydrogen agency, or a headless Shopify storefront developer? Shopify is a great platform for merchants and a frustrating one for agencies who treat every store the same. We build for the operator: custom Shopify private apps that automate back-of-house, public Shopify App Store apps with proper OAuth and billing flows, headless storefronts on Hydrogen when content needs to outrank a stock theme, and theme customization where it earns its place.
We have shipped Shopify integrations across indie brands, growing Shopify Plus retailers, recipe-led specialty stores, and AR/VR brand experiences. The merchant runs the day to day; we build the back-of-house so they do not have to call us every week, and we are not on retainer for store maintenance.
Cases below are anonymized examples of merchant-led builds, not theme reskins.
