About this gig
Build shopify public app shopify private app shopify API integration webhooks
Shopify powers 4.8M+ stores, yet 90% of custom app builds fail from weak API integration and messy backend code costing merchants real revenue every month.
Broken integrations slow your store, frustrate customers, and stall growth. As a skilled Shopify app developer, I turns that chaos into a smooth, scalable system.

FAQ
What's the difference between a Shopify public app and private app?
A public Shopify app is listed on the Shopify App Store and used by multiple merchants, while a private/custom app is built exclusively for your store. I develop both based on your business needs.
Do you handle Shopify API integration with third-party tools?
Yes, I integrate Shopify API with CRMs, ERPs, shipping tools, payment gateways, and other external platforms to automate your workflow.
Can you build a custom subscription or recurring payment app?
Absolutely. I build subscription apps, recharge apps, and recurring payment systems tailored to your Shopify store's billing model.
Will I own the app and source code after delivery?
Yes, full ownership and source code are transferred to you once the project is completed and payment is finalized.
Do you build apps for Shopify Plus stores?
Yes, I have experience developing custom apps and API integrations specifically for Shopify Plus merchants with higher scale needs

Yes, every custom Shopify app I build includes a clean, functional admin panel for managing settings, data, and app features.
Do you help with Shopify App Store submission?
Yes, I can prepare and guide your public app through Shopify's App Store review and approval process as an add on service.
What tech stack do you use for Shopify app development?
I use Node.js, Remix, Shopify CLI, GraphQL Admin API, and AWS for backend deployment to ensure fast, scalable performance.
Can you convert my website into a Shopify app or store?
Yes, I offer website to app conversion and full Shopify store design/development for brands migrating or launching fresh.
