Selected work
A selection of Shopify stores, integrations and digital solutions delivered across my professional experience.
Shopify App Development
AYD Returns & Exchanges, live on the Shopify App Store, is a multi-tenant Shopify public app for self-serve returns, exchanges, gift returns and store credit via a Theme App Extension. A rules engine approves, holds and refunds returns, and a prepaid Royal Mail label and QR code are sent on approval. Merchants run it all from an embedded Admin app built with Shopify's Polaris web components, with Shopify Flow, Sidekick, staff roles and a returns API on the top plan.
Shopify App Development
Building AYD Checkout Rules & Upsells, a multi-tenant Shopify public app for checkout rules, discounts and upsells. Merchants block checkout with custom messages, hide or rename shipping options, reorder payment methods, and create tiered, buy X get Y and free shipping discounts, all on Shopify Functions and set up from 60+ templates. Checkout UI extensions add banners, thank-you page offers and, on Shopify Plus, upsells.
Shopify Headless Commerce
Built a custom Shopify Hydrogen storefront serving three security-industry brands, Professional Security, Armatus and Bridgegate Security, from one shared Shopify backend. Each brand resolves from its URL path, swapping header, footer and theme per brand. Also built a restricted trade ordering channel, a pay-in-full vs. pay-in-instalments toggle with no third-party app, and a monthly auto-rotating employee password gate.
Shopify 2.0
Designed and built Dip and Doze's new bespoke Shopify store from the ground up: dedicated landing pages with dynamic sections and blocks rendered through metaobjects and metafields, giving full control over layout. The product form supports dynamic variant-level add-on products, plus size and colour siblings for easy cross-navigation between related variants. Sale automations, also powered by metaobjects, update the whole site for the exact time period of a sale.
Full-Stack Website
Designing and building the Behrens Group's enterprise website from the ground up: a fully bespoke build with multiple landing pages for the group's different businesses, all managed through a custom-built admin panel that lets content be updated without touching the source code. Built from scratch with React and Tailwind CSS, hosted on Cloudflare Pages for complete control over performance and architecture, with blog publishing and form submissions handled through Cloudflare Workers.
Shopify 2.0
Shopify App
Designed and built the Official Snooker Store for WPBSA on Shopify, connected to the ERP for orders, inventory and fulfilment. I also built a real-time single sign-on bridge between the store and WPBSA's new Play Snooker app, so app users shop without logging in twice. A custom API syncs PlayPlus membership status the instant it changes, applying the 10% subscriber discount, replacing a $149/mo app that only updated status at login.
Shopify 2.0
Built and maintain multiple storefronts, including The Hybrid Games, Valor, Sale Sharks, The Sugar House and LUSU, all hosted on a single Merch Team Shopify store. Each one looks, feels and functions like a fully independent store, with its own theme, custom sections and logic (All of them run their own custom cart flows), while session handling keeps shoppers locked to the storefront they landed on. Every storefront still syncs back to the same ERP behind the scenes.
