Full-cycle Shopify app development

I develop Shopify apps that take your store beyond theme capabilities. When merchandising logic, order processing, or supplier integration can no longer be solved with Liquid edits, I design and launch a full-fledged app: an embedded admin app inside the Shopify dashboard, a private or custom app for a single store, or a public app packaged for the App Store with recurring billing. Everything is written against current Admin and Storefront GraphQL APIs, follows Shopify App Bridge and Polaris conventions, and passes the review checklist before it reaches your account.

I handle the part of the work that makes an app reliable rather than a demo. I configure webhooks for orders, products, carts, and app uninstall with HMAC signature verification and idempotent handlers, so if Shopify resends something, nothing gets processed twice. I add checkout extensions and Functions for custom discounts, shipping options, and validation, connect your ERP, CRM, warehouse, or payment service through clean API layers, and correctly handle OAuth, session tokens, request limits, and pagination. If you're selling the app to other stores, I implement the Billing API with trials, usage-based pricing, and upgrade scenarios.

You get readable code, a staging build for testing, deployment notes, and a brief handoff call so your team can maintain everything. I can start from your brief or help you write it, pick up a stuck app, or prep a finished build for App Store publication. Describe what scenario your store is missing, and I'll honestly tell you where you need an app, where a Function will do, or where a light script is enough.
