Magento 2 REST API slow – missing pageSize and wrong filtering
An ERP integration with the shop via REST API was getting slower over time. Fetching the orders list via API took 45 seconds. The endpoint was returning the entire order history instead of the last 24 hours. Fix time: 3 hours.

Command pattern – command queue, undo/redo, Magento 2 MessageQueue
The Command pattern encapsulates a request as an object, allowing operations to be parameterised, queued, logged and undone. In Magento 2 this pattern is the foundation of the MessageQueue system – each message is a Command executed asynchronously by a consumer. I show the implementation from the classic version through to integration with the Magento queue.
