About this gig
Looking for a powerful custom Shopify app or seamless API integration? You are in the right place!
I build secure, scalable, and fast Shopify applications that run directly inside your admin portal. Whether you want a private app to automate internal operations or a public app ready for the Shopify App Store, I write clean code using modern tech stacks like Remix, Node.js, and React (Shopify Polaris UI).
What I Can Do For You:
- Build private or public custom Shopify apps from scratch.
- Integrate complex third-party REST/GraphQL APIs and webhooks.
- Implement custom checkout extensibility, tailored discount logic, and cart rules.
- Sync data automatically with external systems (CRMs, ERPs, inventory portals).
- Fix broken webhooks, API tokens, authentication, and general app bugs.
Why Choose Me?
I specialize strictly in Shopify software development. Your app will be fully optimized, securely hosted, and rigorously tested to prevent runtime errors.

FAQ
Do you build private apps or public Shopify apps?
I develop both! I can build a private app explicitly for your store's internal workflow or a fully public application structured for submission to the official Shopify App Store.
Which frameworks and languages do you use to build apps?
I build secure applications using Node.js, TypeScript/JavaScript, and HTML. I strictly use Remix and React (Shopify Polaris), which are Shopify's officially recommended frameworks
Will you help host and maintain the backend database?
Yes. I can set up and securely connect your application backend to cloud database platforms like Firebase, Supabase, or AWS. App hosting configuration can be added as a gig extra.
Can you update my store for Checkout Extensibility?
Absolutely. I write custom app extensions that tap directly into Shopify’s modern Checkout Block API, enabling custom features, field validation, and dynamic loyalty rules securely.
Do you provide the complete application source code?
Yes, full clean source code delivery is included across all three packages. You will have 100% complete ownership of the repository and deployment files once the order is finalized.
