- Teams adding App Bridge admin UI, Functions, or agent-ready catalog surfaces.
What you get
- Embedded admin with App Bridge and Polaris that feels native to Shopify

- Billing, dunning, and analytics hooks that match your pricing model
- Protected customer data review support when your app needs it
- Optional agentic commerce / UCP readiness so agents can shop safely

Free tools I built for this work

▸ Tool
Shopify Webhook HMAC Verifier
Check a webhook, app proxy or OAuth signature against your client secret, constant-time, in the browser. When it fails, it tells you the likely cause.

▸ Tool
Shopify GID Decoder
gid://shopify/Product/123 in, resource type and legacy numeric ID out — or the reverse. Handles the base64-encoded IDs older APIs still return.
-
▸ Tool
Shopify Rate Limit Planner
GraphQL Admin, REST or Storefront, by plan: throughput, time to sync N records, batch size and concurrency. Paste a response to use your real costs.
-
▸ Tool

Questions, answered.
Public app or private Plus app?
Either. Public apps need billing, listing, and review discipline. Private Plus apps prioritize deep merchant workflows and data access. The engagement shape changes; the engineering bar does not.
Do you handle App Store review?
I build to Shopify's review expectations (scopes, protected customer data, billing UX) and help you prepare the submission. You own the Partner account and final submit.
Can you work with an existing Remix or Laravel app?
Yes. Many projects extend an in-progress app: fix webhook reliability, finish billing, or add App Bridge surfaces without a full rewrite.
What about agentic commerce / UCP?
If your roadmap includes agents shopping or catalog tools for AI clients, we can design those surfaces into the same engagement or as a follow-on sprint.
