About this gig

I've built and shipped Shopify apps that live merchants use daily including a spin-wheel discount app and a sales notification app, both running on real stores.

Most Shopify developers are theme people. I'm a backend engineer, which matters once your app needs webhooks that don't drop events, background jobs that survive a traffic spike, or an integration with something outside Shopify.

What I build:

  • Embedded admin apps with Shopify Polaris and the Admin API
  • Webhook handling that's reliable verified, queued, idempotent
  • Billing API integration for subscription and usage charges
  • Third-party integrations: fulfilment, ERP, CRM, email platforms
  • Background jobs and bulk operations that don't time out
  • Fixing and finishing apps another developer left half-built

I also run my own Shopify store, so I understand the merchant side, not just the API docs.


Before ordering: message me with what your app needs to do. If it's something an existing app in the App Store already does well, I'll tell you building from scratch isn't always the right call.
