About

I'm Robert Foster, a Shopify Plus developer.

I've built on Shopify for 12 years, the past six exclusively on Plus. I do two kinds of work.

Build

I build features stores often get from apps, like bundle pricing, a store locator or a review display, with Shopify's own tools.

If you bring a design, I'll build the sections and pages from it.

Performance

I go through every app and script your store loads and work out which ones earn their place. I measure the page before and after each change.

How I got here.

2014–2016

Two Shopify stores I founded

I founded two Shopify stores in April 2014 and built, ran and maintained them until August 2016.

2016–2020

Freelance

I worked as a freelance Shopify developer, on stores that ranged from startups to Shopify Plus clients.

2020–2023

A century-old leathercraft retailer

For three years I was the only Shopify Plus developer at a company with more than 100 retail stores. I launched four international Shopify Plus storefronts there in four months: U.S., Canada, Spain and an International site.

2023

FosterUI

I started FosterUI in September 2023.

Why I build this way.

Early on, working on client stores, I noticed a pattern. A new feature usually meant a new app, and as the apps piled up, the store often got slower.

App marketplaces are built around adding apps, and each one solved a real problem the day it went in.

Over time, those apps add up, and nobody's job is to look at all of them together.

That's why I check what Shopify can already do before anything gets built or installed.

Have something you want built?

Describe the feature, or the app it would replace, and pick a time for a free 30-minute call. I send you a fixed-price quote within 4 hours of the call, or of anything I ask you for on it.
