Apex Masterclass

Server-side Salesforce, done properly

Apex is the strongly-typed, Java-like language that powers custom business logic on the Salesforce platform. This masterclass takes you from language fundamentals to production-grade patterns used on real enterprise teams. We treat Apex the way senior engineers do: bulk-safe by default, governor-aware, and covered by meaningful tests rather than assertions that only chase a percentage.

You'll master collections, write efficient SOQL and SOSL, and understand DML and the notoriously tricky save order of execution. We build triggers using a maintainable handler pattern, then bulkify everything so it survives a 200-record data load. The async chapters cover Future methods, Queueable, and Batch Apex with the trade-offs that decide which one to reach for. Finally we cover testing to 75%+ coverage the right way, with test data factories and assertions that actually verify behaviour.

Prerequisites: comfort with basic object-oriented programming and a Salesforce org. Outcome: you'll be able to design, write, and test Apex that scales, passes code review, and deploys cleanly. This is a paid, members-only course; the first lesson is free to preview.
