Shopify Custom App & Integration Development
Custom Shopify development for stores that need functionality beyond the app store: private apps, API integrations with your CRM or ERP, and Liquid theme customization.
When the app store isn't enough
Shopify's app ecosystem is huge, but stacking apps has costs: monthly fees, slower storefronts, and data spread across tools that don't talk to each other. Custom development makes sense when you need:
- an integration no app offers, or one app plus three workarounds
- custom logic tied to your own systems (CRM, ERP, warehouse)
- theme changes your current theme can't support cleanly
What I build
- Custom (private) Shopify apps built on the Admin API and webhooks
- API integrations: orders, customers and inventory synced with CRMs and ERPs, using the same reliability patterns I use for API integration on WordPress
- Liquid theme customization: new sections, metafield-driven content and Online Store 2.0 templates
- Platform moves: Shopify ↔ WooCommerce migration in both directions: to WooCommerce for full ownership of your code and data, or to Shopify for hosted simplicity.

Relevant experience
A lot of Shopify work comes from stores paying for four or five apps to cover functionality that's really one integration's worth of work — consolidating that down is usually the better long-term move, both for cost and for reducing what can break.
Questions I get asked
Do you build public Shopify apps?
No. I build private, store-specific apps for a single business, which are faster to ship and easier to maintain.
Should I stay on Shopify or move to WooCommerce?
It depends on how much custom functionality you need and who should own the code. I'll give you an honest comparison, and staying on Shopify is often the right call. For WooCommerce-specific work, see WooCommerce development.
Can you customize my existing theme?
Yes. I add sections and templates to your current theme rather than replacing it, unless a rebuild is clearly cheaper.
