I will build a custom shopify app or api integration for your store
Nihal
About this gig
I build Shopify apps and API integrations that keep running after you stop watching them.
WHAT I BUILD
Custom Shopify apps with OAuth install, webhooks and the Admin API
Your store connected to an ERP, accounting system, CRM or 3PL
Two-way order, inventory and customer sync
Scheduled jobs that pull or push data, with retries and error alerts
Repairs on an integration that keeps breaking
HOW IT WORKS
You tell me the two systems and what should move between them
I send back a short plan naming the exact endpoints and the edge cases
I build it, test it on real data, and hand over the code plus setup docs
You get the source. No lock-in and no monthly fee to me.
Stack: Python, Node, Shopify Admin API, GraphQL, REST, webhooks, Odoo, QuickBooks, Zoho.
Based in Doha, Qatar (GMT+3). I work with clients in the Gulf, Europe and the US.
Not sure it fits? Message me with what you have and what you want to happen. I will tell you straight whether I am the right person for it.

Shopify developer and automation engineer. I manage a live Shopify store for a furniture retail group in Qatar — payment gateway integrations, theme code, order systems, the full stack. That means I fix stores the way someone who actually runs one does: find the root cause, fix it clean, explain it plainly. I work in Liquid, CSS, JavaScript and Python. If your store is broken, message me — I'll tell you honestly whether I can fix it before you spend a riyal.

FAQ
What do you need from me to start?
Your store URL, a Shopify custom app access token, and API access to the other system. If you do not have credentials yet, message me first and I will send the exact steps and the exact scopes to request.
Do I get the source code?
Yes. Everything I write is yours, delivered as a repo or a zip with setup instructions. No license fee, no lock-in, and nothing that only runs on my machine.
Can you fix an integration someone else built?
Yes. Send the repo or the app and tell me what is breaking. I will review it and tell you whether repairing or rebuilding is cheaper before you place an order.
What if the API changes and it breaks later?
Every build has error handling and logging so failures are visible instead of silent. I also cover 14 days of free support after delivery for anything that breaks in the code I wrote.
Will this slow down my store?
No. The work runs outside your theme, on webhooks and scheduled jobs, so nothing extra loads on the storefront. If a job needs to touch the theme I tell you before I do it.
