Aaron Magee

Hello there! I’m Aaron, a Shopify developer with 10+ years of experience building custom Shopify themes, developing apps and improving existing stores. I'm also a Shopify Partner and the developer behind two published Shopify apps: Password Lock Products and Pages, and Upload Field: Forms and Products.

I work with ecommerce businesses that need more than basic theme customisation. Whether it's building a custom Shopify theme, developing bespoke functionality, improving storefront performance or integrating external services, I can help turn complicated requirements into practical, maintainable solutions.

What I can help with:

• Custom Shopify theme development using Liquid, JavaScript, HTML and CSS

• Shopify 2.0 theme development, rebuilds and migrations

• Figma to Shopify development and responsive implementation

• Shopify app development and custom storefront functionality

• Custom Shopify sections, templates, snippets and metafields

• Product, collection, cart and landing page customisation

• Shopify Plus development and advanced storefront requirements

• Shopify speed optimisation and Core Web Vitals improvements

• Theme performance audits, app bloat and unnecessary script clean-up

• API integrations and connecting Shopify with external services

• Klaviyo integrations, including custom forms and data connections

• AJAX carts, product bundles, custom forms and other bespoke features

• Ongoing Shopify development, maintenance and technical support

Experience across different ecommerce businesses:

I've worked with Shopify stores across a range of industries and business models, including campaign-led documentary releases, sustainable retail brands, product-heavy catalogues, fashion, lifestyle and subscription businesses.

This includes everything from complete storefront builds and theme customisation to ongoing development, complex product requirements and improving existing ecommerce experiences.

Examples of the work I handle:

• Building custom Shopify theme architecture using Liquid, JSON templates, sections, snippets and metafields.

• Turning Figma designs into responsive Shopify sections and templates with practical merchant controls.

• Improving product and collection pages for stores with more complex browsing and buying journeys.

• Reducing app bloat, improving script loading, implementing lazy loading and fixing layout stability issues.

• Developing custom Shopify functionality, including AJAX carts, bundles, forms and integrations.

• Connecting Shopify with external platforms and services, including Klaviyo.

• Supporting regular campaign, product, design and content updates for growing ecommerce stores.

Tech stack and tools:

• Themes: Liquid, CSS, JavaScript, Shopify CLI

• Apps: React Router, TypeScript, Prisma, Shopify Functions, Polaris, hosted on Render

• Speed and accessibility checks with Lighthouse, and Klaviyo integrations

Projects I’m proud of:

• Custom theme work for Original Duckhead, CREATORVC and Water Gardening Direct. The case studies are on idwithin.com.

• Upload Field: Forms & Products, a published Shopify app that lets customers upload files on product pages. I built it after a client needed it. Integrating with Klaviyo and other form builders.

• Password Lock Products & Pages, a live app that lets merchants password protect products and pages, including blocking purchases at checkout.

• idwithin.com itself, a working Shopify store that doubles as my portfolio, so you can test the cart, filters and search and anything else yourself!

I’m also preparing this theme to be submitted for the Shopify Theme Store.

How I work:

I keep the process straightforward. You bring me the store, design or problem, and I'll work out the cleanest Shopify approach before building it in a way that's practical to maintain after launch.

I'm comfortable working on existing themes, troubleshooting code written by others, developing new functionality or taking a project from Figma through to a finished Shopify storefront.

I also understand that not every problem needs another paid app or an unnecessarily complicated solution. Sometimes the better option is a small, well-built piece of custom code.

If you're looking for a Shopify developer who can work directly with your theme, understand the underlying code and help you build or improve your store, send me a message.

Tell me what you're working on, or send me your store URL and explain what's slow, broken or needs improving. We can work out the best way forward.
