I will develop a custom shopify app for your store with remix and polaris


About this gig
Need Shopify to do something it doesn't do out of the box? That's a custom Shopify app.
I've built and published two apps on the Shopify App Store: COD Shield and UpAfter AI. So I've been through all of it: OAuth, webhooks, App Bridge, the billing API, extensions, and Shopify's app review. Most sellers here have never shipped one.
WHAT I BUILD
* Private or custom apps for a single store
* Public apps ready for App Store submission
* Checkout and post-purchase UI extensions
* Shopify Functions for discounts, delivery and payment rules
* Embedded admin apps with Polaris
* API integrations with ERP, CRM, 3PL and payment gateways
STACK
Remix, Polaris, Node and NestJS, GraphQL Admin API, Prisma. Deployed to Railway or your own infrastructure.
HOW WE START
Message me before ordering. Tell me what your store needs to do that it can't do today. I'll tell you honestly whether an app is the right answer. Sometimes a theme edit or an existing app is cheaper, and I'll say so.
You get clean, documented code that you own.

FAQ
Do I need a custom app, or will an existing app do?
Message me first and describe the problem. If something on the App Store already solves it, I'll point you there. I'd rather turn down a bad fit than deliver something you didn't need.
What's the difference between a private app and a public app?
A private (custom) app is installed on your store only. A public app goes through Shopify's review and can be listed on the App Store for other merchants. Private is faster and cheaper; public is for building a product.
Do I own the code?
Yes. You get the full repository, documented, plus deployment instructions.
Will you need access to my store?
Yes — a collaborator account or a development store. I'll never need your customer data.
Can you also do checkout extensions and Shopify Functions?
Yes. Both are covered in Standard and Premium depending on complexity.
