Over deze dienst

Shopify only. Nothing else.


This is the work no app on the App Store actually sells and no theme editor can do. Custom apps, Shopify Functions, checkout UI extensions, and the API integrations that make Shopify agree with your other systems.


What I build here:

- Shopify Functions: custom discounts, shipping rules, payment rules, cart transforms

- Checkout UI extensions: fields, upsells, delivery instructions, custom validation

- Private and custom apps with a real admin interface inside your Shopify admin

- Integrations with your ERP, CRM, 3PL or warehouse over the GraphQL Admin API

- Webhooks that retry instead of silently failing at 2am

- Rescue work on a half finished app your last developer walked away from


Three of my own apps are live on the Shopify App Store and I support them daily. Same hands, same code.


Before you order, message me what you need. I will tell you if a Function solves it in a day, if it needs a full app, or if an existing app already does it and you should just buy that. If it is not worth building, I will say so.

Shopify only. Nothing else. I build what Shopify won't do out of the box: custom apps, checkout extensions, Shopify Functions, theme work, API, integrations. Three of my own apps are live on the Shopify App Store, supported daily. You get someone who has already shipped, not someone learning on your budget. Work I take most often: - A feature no app on the App Store actually sells - "That isn't in the theme settings" - Shopify and your ERP, CRM or 3PL disagreeing on stock - A half-finished build your last developer walked away from Send me your store URL and I'll tell you what it takes.
