Budget: 6000 UAH Deadline: 5 days

My name is Mykola Mohilnyi, I am a web developer with 4 years of experience, including working with Shopify API and creating custom solutions for specific tasks. I am ready to implement your functionality:
Creating a private Shopify app
Access to 3 stores owned by the same owner
Retrieving orders of a specific customer from all three stores
Combining this data into JSON/HTML
Displaying on the storefront the user profile in any of the stores

Good day) Yes, everything is clear, the task is straightforward, I have done similar before. I can develop a private Shopify app. We will connect all 3 stores, pull orders for a specific customer, compile them into one JSON, HTML, and display it in their profile on any of the stores. Everything will work automatically when the user logs into their account.

Hello, Viktoriya! An interesting case, but I see the implementation a bit differently than described, there is no need for a json that will be sent somewhere, since a direct seamless integration between stores can be done, with the possibility of scaling.

Hello! I am Margo, specializing in creating private Shopify apps and integrations between multiple stores. I am ready to implement your turnkey app — extracting orders by customer from 3 stores and displaying them in the user profile on the storefront.

What I will implement:
A private Shopify app authorized on 3 stores owned by the same owner.
Retrieving orders for a specific customer (by email / ID) via Shopify Admin API.
Aggregating orders in JSON or HTML format, combining data from 3 stores.
Integration with the storefront user profile — automatically displaying the entire order history.
Speed optimization of requests and secure data transmission to the front end.
Technical approach:
Backend: Node.js / Python (FastAPI) or Ruby (choice).
OAuth for access to each store (or private tokens).
Injection of JSON/HTML into the user profile via Liquid/JS or storefront API.
Timeline: 7–10 working days
Estimated cost: from $300 to $450 (depending on the integration method into the storefront)
Ready to discuss details: how exactly the user is identified across stores (email, phone, custom ID?), in what format the history should be displayed, and whether scaling to other stores is planned.

I will be happy to implement a stable and scalable Shopify solution for you.

Best regards,
Margo Expand
