I will develop a custom shopify app you can resell or use


About this gig
Need functionality the Shopify App Store doesn't sell? I'll build a custom app that does exactly that thing well.
I'm the founder of Opus Technologies, building commercial Shopify and WooCommerce products. I work in the current stack: Remix, Node, Polaris, App Bridge, Shopify CLI, GraphQL Admin API, and webhooks. Your app installs cleanly in the merchant admin and follows Shopify's own patterns, which is what keeps it approvable and maintainable.
What I build:
- Private and custom apps for a single store
- Embedded admin apps with Polaris UI
- Order, fulfilment and courier automation, including COD workflows
- Metafield and metaobject tooling, bulk editors, custom reports
- Theme app extensions and app blocks
- ERP, CRM, SMS, WhatsApp and shipping API integrations
- Public apps built to App Store submission requirements
You get the full repo, deployment setup, and a handover doc. No black boxes.
Send me a brief before ordering. I'll tell you whether a custom app, a theme app extension, or an existing App Store app is the right answer, even when that answer costs you less.

FAQ
Custom app or public app?
Custom is for one store and needs no Shopify review. Public is for selling to many merchants and must pass review. I build both; tell me which outcome you want.
Do I need hosting?
Yes, embedded apps run on your infrastructure. I deploy to Vercel, Fly.io or Railway and hand over the credentials.
Can you guarantee App Store approval?
Nobody honestly can. I build to Shopify's published requirements and handle the review feedback rounds with you.
Do I own the code?
Yes, the full repository transfers to you.
