About James Cartwright
I help growing Shopify brands build stores that convert well, run smoothly and are ready to scale. With 25 years of experience in web design and development, including ten years running my own agency, &beyond, I've worked with eCommerce businesses across the UK and the United States. I'm also a bi-vocational church minister, serving at Generations Church alongside my development work.
My clients are typically established or fast-growing direct-to-consumer brands, including subscription businesses, that have outgrown off-the-shelf themes and apps. They need custom functionality, a better customer experience or a clearer technical strategy, and want a developer who understands both the code and the commercial goals behind it.
I specialise in eCommerce tech-stack consultation, strategy and implementation, along with front-end development on Shopify. That includes theme customisation in HTML, CSS, JavaScript and Liquid, Shopify 2.0 custom theme development, custom Shopify apps in Node.js and React, and bespoke front-end builds in Next.js.
The result for clients is a store that's easier to manage, faster and more reliable, with customer journeys designed to lift conversion and average order value, and a setup that supports growth rather than holding it back.
I work with a small, select number of clients on an ongoing basis, so you get direct, responsive support from someone who knows your business. If you'd like to explore working together, please drop me a message.
