About this gig

Checkout and Order Status UI extensions run in a sandboxed environment where one wrong import silently breaks the render, with no error shown. Most developers avoid this part of Shopify entirely.


Heads up if you are on a non-Plus plan: Shopify removes checkout.liquid and Additional Scripts on August 26, 2026. After that date your store auto-upgrades and any legacy checkout customization is gone, not paused, gone. If you are still on old scripts, that date is your real deadline to migrate. If you are close to that date, check the Extra Fast Delivery optionI shipped one to production myself: a returns app with OAuth install, Billing API (a real subscription plan approved by Shopify), order webhooks, an Order Status UI extension, and a working money loop. It's live today, not a demo.


What you get:

  • A working extension deployed to your development or live store
  • - Clean, tested code -- I write tests before the feature, not after
  • - Clear communication in English or French

What I'll tell you upfront: if an extension isn't the right technical fit for what you're building, I'll say so before you order -- not after.


Message me with your use case and I'll tell you exactly what's involved.

I help Shopify merchants ship custom apps and Checkout/Order Status extensions -- the sandboxed part of Shopify most developers avoid, where one wrong import breaks the render with no error shown. Proof: I shipped one to production myself. A returns app with OAuth, Billing API (approved by Shopify), order webhooks, an Order Status extension, and a working money loop -- live today, not a demo. What I build: custom Shopify apps, checkout extensions, GraphQL Admin API, GDPR endpoints, French/English localization -- I'm a native French speaker. Test-first always. I answer every message myself.
