CORE Transformers
A UX/UI rebuild and custom lead-generation funnel for a US electrical manufacturer.
Custom eCommerce software development
We build the software behind commerce: B2B portals, ERP and warehouse integrations, custom Shopify apps, and the middleware that connects a storefront to the systems behind it. Senior developers in Node.js, Java and Go, working inside your team.
Capabilities
What we build
We work with retailers, wholesalers and manufacturers whose commerce runs on more than a storefront, and build the platforms, integrations and back-end services behind it.
Enterprise commerce platforms
Salesforce Commerce Cloud, custom platforms and the systems large retailers already run. Senior developers who join your team and improve what exists, without replatforming everything at once.
ERP and systems integration
Connecting storefronts to ERP, warehouse, PIM and finance systems, with the middleware and error handling that keeps orders flowing when something upstream fails.
B2B portals and ordering
Customer-specific pricing, quoting, approval workflows and account management, whether that's a Shopify B2B build or a custom platform.
APIs and back-end services
Node.js, Go and the services behind custom commerce systems, designed for the load they'll actually see — including the AWS infrastructure they run on, provisioned with Terraform.
Custom Shopify apps
Private and public apps, Shopify Functions, checkout extensions and the automations that remove manual work from a merchandising team.
Case studies
Cult Beauty
Salesforce Marketing Cloud integration as part of a large-scale CRM project.

FAQ
Common questions
Can your developers work inside our existing team and codebase?
That's how most of our embedded work runs. Our developers join your Slack, your standups and your sprints, work in your repository and follow your review process. You get senior eCommerce and front-end expertise without hiring for it, and your own developers stay on the product.
Do you work with enterprise platforms and established codebases?
Yes. Our developers are all senior, across Node.js, Java and Go, and we work in systems that have been running for years, including Salesforce Commerce Cloud. Most of what we do is improving what exists, not arguing for a replatform.
How do you handle security reviews and code ownership?
You own the code. We work in your repository under your review process, and we're used to security reviews, access controls and whatever your organization requires before external developers touch a system.
Can you start with a small piece of work before we commit?
Usually the sensible way to start. A defined piece of work lets both sides see how we operate before anyone signs up to a long engagement. Several of our long-term partnerships began that way.
