Project description:
"I already have the UI of my Shopify app developed (AI-designed) — this project focuses only on backend and integration work, not a full build from scratch.

I’m looking for a Shopify app developer experienced in building and publishing public Shopify apps that can be installed and used by merchants from the Shopify App Store.

This is a long-term collaboration, as I’ll be partnering with multiple Shopify apps in the future and will need ongoing integration and cross-promotion support between them.

Project Scope:

Required Integrations

Shopify Backend Setup

Shopify APIs

Shopify OAuth 2.0 Authentication Flow

Zapier Automation Integration (for workflows and event triggers)

Integration with other third-party apps (data sync, automation, and marketing tools)

Additional Requirements

Assistance with Shopify App Store approval and publishing

Guidance to achieve the “Built for Shopify” badge

Implementation of a cross-promotion banner system across apps for mutual exposure and growth

Important Clarification

When I say Shopify apps, I mean public Shopify apps available in the Shopify App Store that merchants can install and use,
not Shopify stores or websites.
Please do not submit proposals related to store or website development — this project is strictly for Shopify app integration and publishing.

What I’m Looking For

Proven experience building and publishing Shopify public apps

Deep knowledge of Shopify APIs, OAuth 2.0, and Shopify Partners dashboard

Familiarity with Zapier and automation integrations

Ability to assist with Shopify App Store approval and Built for Shopify badge

Long-term mindset — open to collaborating on multiple app integrations and cross-promotion projects

Deliverables

Fully functional backend integration (Shopify + APIs + OAuth + Zapier)

Guidance through the app approval and publishing process

Cross-promotion banner system setup for future linked apps

Please Include in Your Proposal

Your timeline estimate to complete all integrations and publish the app

Your total cost estimate (including ongoing support if needed)

Links to Shopify apps you’ve published (if available)" (client-provided description)
