Hi! I'm Ian, a Shopify and full-stack developer with 6+ years of experience. I build the things your off-the-shelf Shopify apps can't quite do.

What I can help with:
- Custom Shopify apps and theme app extensions
- Figma to Shopify theme builds
- Product customizers, cart and checkout customizations
- Integrations with inventory, ERP, 3PL, and other systems
- Automations and AI workflows for e-commerce ops
- Backend services and internal tools (Node.js, NestJS, Next.js, PostgreSQL)

How I work:
- Quick call to understand the problem, then a fixed price so you're not stuck with an open-ended hourly bill
- Async-friendly with regular updates
- Clean handover and documentation, so your team isn't dependent on me after launch

Google Cloud Professional Cloud Architect certified.

Rate: From USD 45/hr, or fixed price per project

I usually duplicate the live theme, work on the copy, then publish it after checking. The problem is that the merchant sometimes changes sections or content in the live theme's customizer while I'm working, and those changes can get lost when I publish the copy. I've looked at the GitHub integration and Shopify CLI with git, but merging customizer JSON changes still feels messy.
How do you handle this?
Do you freeze content edits during development, pull the live theme before publishing, or something else?

I just got my first app approved: Craftedly: Ask Your Store. It emails merchants a store summary every Monday morning and shows insight cards in the admin. Solo build on Remix, hosted on Railway, Postgres on Supabase, email through Resend.

Here are a few things that cost me time, in case they save you some:

1. Dev sessions were overwriting my production App URL.
My shopify.app.dev.toml had automatically_update_urls_on_dev = true. Every time I ran a dev session, it swapped the live app URL for a Cloudflare tunnel URL that died when I stopped. The fix was setting it to false and adding include_config_on_deploy = true to the production shopify.app.toml, then redeploying.

2. Supabase’s “Unrestricted” table warning.
If your tables live in Supabase’s public schema with RLS off, they’re exposed through its API. Enabling RLS on every table fixed it. My app connects as the database owner, so nothing in the app broke.

3. Test data and app review.
I had placeholder data in one insight card (customer platform breakdown). I pulled it before submitting rather than risk a rejection, and I’m now choosing between a Web Pixel extension and ShopifyQL to populate it with real data. If you’ve done either, I’d like to hear which held up better.

Next up: multi-store reporting for agencies.

What tripped you up on your first submission?
