About

Built by someone who works inside Shopify and subscription data every day.

International Interactive is run by Matt Ammirati, a Shopify developer with a background in data engineering. That combination means stores aren't just built to look good at launch — they're built with the customer and subscription data underneath in mind from day one.

Most of the work here centers on subscription commerce: Recharge and similar subscription apps, repeat-purchase flows, and the kind of store architecture that makes recurring revenue easier to see and easier to grow. Store audits, GraphQL/API integration, and point-of-sale work round out the rest.

For some clients that's a single project. For others it's ongoing technical ownership — being the one person who knows the store's codebase, its apps, and the reasoning behind past decisions, rather than whoever's available that week.

Process

How a project usually goes

01

Audit

A look at the current store, theme, apps, and data setup to find what's actually costing revenue or slowing growth.

02

Build

The migration, rebuild, or subscription system gets built and tested against the store's real traffic and customer data.

03

Support

Ongoing technical ownership for stores that want a consistent point of contact rather than a one-off handoff.
