Backend & API integrations (ERP, suppliers, 3PL)
Your store, suppliers, warehouse and other systems kept in step automatically, so nobody copies stock or orders by hand.
Custom Shopify app development
When no app does what your store needs, I build one just for you: storefront features, checkout logic, admin tools and the backend behind them.
Public App Store app development
From the idea to an approved App Store listing. I run apps of my own, so I know the review rules from my own submissions.
Content & design
Catalogue filling & product data import
Your catalogue loaded and kept tidy: products, variants, images and metafields imported from spreadsheets, suppliers or an old platform.
Migrations
Shopify → WooCommerce migration
Leaving Shopify for WooCommerce without losing what you built: the catalogue with variations, content and translations, and every URL that brings in search traffic.
Shopify ↔ BigCommerce migration
Moving between Shopify and BigCommerce with products, metafields, pages, the blog and reviews, and with the URL structure kept so indexed pages keep working.
