I build custom Shopify apps, headless storefronts, and backend systems for merchants and agencies who've outgrown what themes and off-the-shelf apps can do. Most Shopify problems I solve aren't theme problems — they're logic problems: subscriptions that don't behave, checkout flows that need custom rules, data that needs to sync across platforms, or fulfilment workflows that need automating. That's where I come in. 🛍️ What I Build for Shopify Merchants — Custom Shopify apps (public and private) using React + Polaris — Shopify Admin API, Storefront API, and GraphQL integrations — Headless storefronts with Next.js + Shopify Hydrogen/Storefront API — Checkout extensions and Functions (discounts, payment customisations) — Subscription logic, prepaid plans, and billing pipeline builds — Third-party integrations: Stripe, PayPal, ShipStation, ERPs, CRMs — Webhook handlers, event queues (AWS SQS/Lambda), and serverless APIs — Workflow automation with n8n for order, fulfilment, and notification flows ⚙️ Tech Stack React, Next.js, Node.js, Shopify APIs (Admin, Storefront, Webhooks), AWS Lambda, SQS, Stripe, REST & GraphQL, PostgreSQL, MongoDB, Docker 🏗️ How I Work I don't just write code — I understand the Shopify platform deeply enough to tell you when a custom app is the right call and when it isn't. I've worked on complex subscription migrations, custom payment flows, and multi-system integrations where the Shopify constraints matter as much as the code. I communicate throughout the project, document what I build, and write code you (or another developer) can maintain after handoff. ✅ Right fit if you need: — A Shopify app built from scratch or an existing one extended — A headless/custom storefront that goes beyond standard themes — Backend systems that talk to Shopify via API (syncs, automations, pipelines) — A developer who knows Shopify's quirks, rate limits, and API constraints If you're a Shopify merchant, agency, or startup building on Shopify and need more than a theme developer — let's talk.
