About this gig
Need a Shopify app that does exactly what your store requires without bloated third party subscriptions or fragile workarounds?
I build clean, secure and scalable Shopify apps from scratch and I fix broken or underperforming apps that are slowing down your storefront.
With 10 years of Shopify and fullstack development experience and 60+ apps delivered, I specialize in custom apps for single stores and public apps built for the Shopify App Store. Every build follows Shopifys current API and OAuth patterns, is tested against your theme and ships with clean documentation.
What I can build for you:
Custom (single store) apps
Public Shopify apps
API integrations
Storefront extensions
Bug fixes and rescue work
Why buyers choose this gig:
Shopify native architecture
No unnecessary subscriptions
Review Can you integrate a third-party API?ready code
Honest scoping
Clear communication
Please message me before ordering. Shopify app scope varies enormously between a small custom automation and a full public App Store product and I want to quote you accurately rather than guess.
Respect third-party rights
Please be aware that it is against Fiverr's policies for sellers to include themes, templates, or any other elements that infringe third-party rights or applicable laws in the delivered work. Read more about in our Guide to Responsible Digital Creation.

FAQ
What is the difference between a custom app and a public app?
A custom app is built for a single store and installed privately. A public app is distributed through the Shopify App Store and must pass Shopify’s review, including billing setup and multi-tenant architecture. Tell me which one you need before ordering the scope and timeline are very different.
Can you fix an app that another developer built?
Yes. I regularly debug and rescue third-party or legacy Shopify apps. Share the app files and a description of the issue, and I will confirm whether it is a fix or a rebuild before you order.
Will the app work with my theme and other installed apps?
Yes. I test against your active theme and check for conflicts with your installed app stack before delivery.
Do you handle Shopify App Store submission?
The Premium package includes review preparation structuring the app to meet Shopify’s requirements and walking you through the submission checklist. The actual review decision rests with Shopify, so I cannot guarantee approval, but I build to their published standards.
Can you integrate a third party API?
Yes. API integrations are a core part of this gig, including REST and GraphQL connections to ERP, CRM, inventory and logistics systems.
