Shopify Integration Platform – UK
Developer, Jan 2026 – Present
Project description
- End-to-end integration platform connecting a UK company's on-premise database to Shopify Plus, keeping product, customer, and order data synchronised in both directions.
- Delivered as two independently deployed Azure App Services communicating asynchronously over Azure Service Bus, following Clean Architecture.
- Sole engineer on the project - responsible for backend, frontend, UI design, testing, environment setup, and CI/CD.
Responsibilities
- Designed and built the Sync Engine service: pushes new and updated products and customers to Shopify through the Admin GraphQL API, and ingests Shopify order webhooks, validating and persisting orders back to the on-premise database.
- Designed and built the Integration Tool service with a ReactJS/TypeScript UI for creating and editing products and customers, bulk Excel import/export using ClosedXML, and manual triggering of sync operations.
- Connected Azure-hosted services to the on-premise SQL Server using Azure Relay and Hybrid Connection Manager, enabling secure hybrid connectivity without VPN or firewall changes.
- Decoupled the two services with Azure Service Bus queues, applying retry and dead-letter handling so transient Shopify API failures and rate limiting do not result in lost messages.
- Implemented idempotent order writes and webhook signature verification to handle Shopify's duplicate and retried webhook deliveries safely.
- Secured both applications with Microsoft Entra ID, using app registrations and app role assignment to restrict access to authorised users only.
- Implemented .NET background jobs for scheduled delta synchronisation and reconciliation between the two systems.
- Structured both services with Clean Architecture (Domain, Application, Infrastructure, Presentation) and EF Core, with xUnit test coverage on the Application layer.
- Set up Azure DevOps CI/CD pipelines covering build, automated tests, and multi-environment release to Azure App Service.
- Designed and built the portal UI from scratch using Tailwind CSS and Vite.
- Used Claude as a development aid for code review, refactoring, test scaffolding, and UI design exploration.
