Apex Design Patterns
Explore the Trigger Handler, Service Layer, Selector, and Unit of Work patterns that keep large Apex codebases maintainable, testable, and bulk-safe.
Apex Interview Questions
The governor-limit, OOP, and async Apex scenarios interviewers actually probe, with the reasoning strong answers demonstrate.

The recurring bugs — unbulkified loops, hardcoded Ids, recursive triggers, and swallowed exceptions — that cause most Apex production incidents.
Conditionals and Loops in Apex
Learn how Apex controls program flow with if/else branching, switch statements, and for/while loops, including the governor limits that shape how you write the…
Exception Handling in Apex
Learn how to use try/catch/finally, built-in and custom exception types, and partial-success DML patterns to write resilient Apex code.
Future Methods and Async Apex

Integrating Apex with LWC
Learn how Lightning Web Components call Apex with @AuraEnabled methods, wire adapters, imperative calls, caching, and error handling patterns.
Queueable and Scheduled Apex
Learn how Queueable Apex overcomes future method limitations with chaining and sObject support, and how Scheduled Apex runs jobs on a cron-based cadence.
Security and Sharing in Apex
Learn how CRUD/FLS enforcement, sharing keywords, and the WITH SECURITY_ENFORCED / stripInaccessible tools keep Apex code from leaking data users shouldn't see.
Testing Apex Code
Learn how to write robust Apex test classes, use assertions and mocks, and produce meaningful code coverage that survives real deployments.
The Apex Development Environment
