Backend Engineering & APIs
Architecture, business logic and the services behind your storefront. We build and extend commerce backends, develop APIs and connect systems, with automated testing and performance tuning built into the engineering.
Services
Backend engineering for the moves that matter. We build modern commerce stacks, migrate platforms and data, and connect the systems behind them. From architecture to cutover, we handle the detail that makes your technology work.
From the foundations up.
Backend engineering, from the foundations up
The complex bits behind the storefront. We design the architecture, write the services, move the data and connect the systems. With over 20 years of commerce engineering experience, we get into the detail that makes a modern tech stack work in the real world.

Architecture, business logic and the services behind your storefront. We build and extend commerce backends, develop APIs and connect systems, with automated testing and performance tuning built into the engineering.
Moving to Shopify, commercetools or a composable stack? We map dependencies, rebuild integrations and test the journeys that matter. From staged delivery to cutover planning, we handle the engineering behind the move.
Products, variants, customers, orders and content. We map and transform records, build repeatable imports and check relationships and totals against the source. Moving the data is only part of it; making sure it works in the new platform matters just as much.
Over 20 years of commerce engineering means we know our way around older stacks as well as new ones. We build APIs, adapters and integration layers that connect legacy ERP, databases and bespoke systems to modern platforms. That gives you room to introduce new technology and replace older components in stages, while keeping the systems your business relies on working together.
We turn a set of platforms into a working architecture. Commerce, content, search and payments connected through well-defined APIs, with the custom services and business rules your operation needs.
Stock, pricing, orders and fulfilment need to stay in step. We build the connections between commerce, ERP and warehouse systems, including data mapping, error handling and retries when something needs another go.
From AWS and Azure infrastructure to automated build and release pipelines, we engineer the environment your platform runs on. Monitoring, deployment checks and performance testing help make day-to-day operations more predictable.
We integrate payment providers into the full order journey, from authorisation and capture to refunds and status updates. We work through the callbacks, failures and edge cases as well as the happy path.
Promotion engines, custom rules and the logic that applies them. We connect pricing and promotions to your commerce platform and test how offers behave across baskets, customer groups and order flows.
Content tools that work with your commerce stack. We connect headless CMS platforms, model content and build the APIs and preview workflows that let teams publish without relying on a developer for every change.
Good search starts with good data. We build product feeds, connect search services and handle indexing and updates, so discovery tools can work with the catalogue, pricing and availability behind them.
When the platform needs to do more, we build the missing piece. Custom apps, connectors, migration tools and backend services, from a focused proof of concept through to production delivery.
Our work spans .NET, Node.js and TypeScript services, SQL Server and PostgreSQL data stores, and AWS and Azure infrastructure. We work across existing and modern stacks, building APIs, data pipelines and automated delivery workflows around the needs of your business.
