About
shopexpert since: December 2025Union Works is a small, senior team of Shopify developers specialising in custom app development. We build private, custom and public Shopify apps that power bespoke workflows, complex features and advanced business logic for growing merchants.
Our team of four has been building on Shopify since 2016, with deep experience across the Shopify Admin API, Storefront API, Functions, webhooks, and Shopify POS. We regularly use apps as the backbone for tailored solutions, whether that’s extending checkout and POS behaviour, integrating third-party systems, or creating custom tools that don’t exist off-the-shelf.
We focus on well-architected, maintainable solutions that fit neatly into a merchant’s existing stack. From internal tools and private apps to fully supported public apps, we’re comfortable handling complex requirements and translating them into reliable, scalable Shopify solutions.
