FAQ
What is the difference between a Custom and Public app?
A Custom App is built for your store only to handle private logic, while a Public App is designed for the Shopify App Store to be used by many merchants.
Can you connect my Shopify store to my external CRM or ERP?
Yes, I use API integration and webhooks to sync your orders, inventory, and customer data with any third-party software that has an API.
Do you build Headless Shopify stores using Hydrogen?
Yes, I develop high-performance headless storefronts using Shopify Hydrogen and the Storefront API for a faster, custom shopping experience.
Will my app be hosted on Shopify or my own server?
Shopify apps require external hosting (like Heroku, AWS, or Vercel). I can help you set up the backend server and database to ensure your app runs 24/7.
Can you fix a broken app or an API sync error?
Yes, I specialize in debugging app crashes, fixing webhook failures, and updating legacy Private Apps to the latest Shopify API versions.
