This one enforces bulkification patterns and governor limits from the start, which is exactly what you need if you've ever watched a trigger blow up in production because someone put SOQL in a loop. It covers the full stack: Apex classes and triggers, Lightning Web Components, SOQL optimization, batch jobs, and platform events. The test class examples include 200-record bulk scenarios, not just single-record happy paths. Honestly, the best part is the side-by-side correct vs incorrect patterns for common violations. If you're building on Salesforce or dealing withCI/CD pipelines through Salesforce DX, this keeps you inside platform limits while you work.
