PHP is the main backend language across our WordPress, WooCommerce and Magento work. It’s open source, well-documented and has a massive community behind it.
The flexibility is a strength, but it also means developers need to be disciplined about keeping code clean and maintainable.
When a project needs more horsepower, things like custom APIs, microservices or systems handling a lot of concurrent traffic, we use Go. Google built it for exactly that kind of workload.
Shopify runs its own servers and manages the commerce logic on their end. We don’t have direct access to that. Any back-end customization goes through Shopify’s Admin API, using REST or GraphQL.
If the API isn’t enough for what the project needs, we build custom apps in Node.js or Ruby.
