AI image generation + print-on-demand, inside Shopify
A storefront experience where customers upload a photo, AI turns it into artwork, and the result is ordered as a printed product, fully automated from upload to fulfillment via a custom Shopify app.

The challenge
No app combines customer photo upload, AI generation with polling and quality control, product creation and print-on-demand fulfillment. The flow had to run on the storefront (not the admin), feel instant, and hand orders to the print partner without manual steps.
What I built
- ✓Embedded Shopify app (Express + React) with a theme app extension for the storefront UI
- ✓App proxy endpoints for secure customer photo upload from the storefront
- ✓Leonardo.ai integration: init-image generation with async polling and result selection
- ✓OAuth integration with a print-on-demand API for automatic fulfillment
- ✓Programmatic product creation via the Admin GraphQL API
Result
- →A product that literally cannot exist on standard Shopify became the store's core offering
- →Zero manual steps between customer upload and print order
