Apex & LWC Professional

Apex & LWC ProfessionalDeepen your code craft: async, integrations, events, security, enterprise patterns, performance and a full LWC toolkit.For: Working developers aiming for Platform Developer II

Asynchronous Apex: Move work out of the user's transaction with @future, Queueable (chaining, Finalizers, AsyncOptions), Batch Apex, Schedulable and Apex cursors — and learn to monitor, limit, test and design async jobs that are idempotent and retry-safe.

Callouts and Apex Web Services: Call external REST and SOAP services safely with Named Credentials, handle JSON like a pro, respect callout limits and transaction rules, and expose your own Apex REST and SOAP APIs.

Platform Events and Change Data Capture: Build event-driven solutions on Salesforce: define and publish Platform Events, subscribe with Apex, Flow, LWC and external clients, stream record changes with Change Data Capture, and operate it all within allocations.

Secure Apex: Write Apex that respects the platform's security model: sharing keywords, user mode database operations, FLS and CRUD enforcement, injection and XSS prevention, secrets handling, guest-user and @AuraEnabled hardening, and automated scanning with Salesforce Code Analyzer.

Invocable Apex: Bridging Code, Flow and Agents: Design @InvocableMethod actions that admins can use in Flow, that Agentforce agents and Prompt Builder can call, and that stay bulk-safe, well-described and testable — plus how to call flows from Apex.

Apex Design Patterns and Enterprise Architecture: Structure large Apex code bases with separation of concerns: Service, Domain, Selector and Unit of Work layers, dependency injection, classic GoF patterns adapted to governor limits, metadata-driven triggers, logging, configuration, feature flags and modular packaging.

Debugging, Profiling and Performance: Find bugs and bottlenecks in Apex with debug logs, trace flags, the Developer Console, Apex Replay Debugger and the CLI, then make code faster and leaner: CPU and heap optimization, SOQL selectivity, Platform Cache, ApexGuru and production monitoring.

Component Communication: Design how Lightning Web Components talk to each other: @api properties and methods, CustomEvents and shadow DOM propagation, slots, Lightning Message Service, state managers with @lwc/state, Flow integration and container/presentational architecture, ending with a full master-detail example.

Base Components, SLDS and Styling: Use the Lightning base component library effectively (including a production-grade lightning-datatable), style components the supported way with SLDS 2, global styling hooks and dark mode, understand CSS in shadow DOM and Light DOM, load third-party libraries, and build accessible, responsive UIs.

Navigation, Modals, Toasts and Actions: Wire your components into the Lightning Experience shell: navigate with NavigationMixin and PageReferences, read URL state, show toasts and modals, build quick actions, Flow screen components, console and utility bar integrations, and URL-addressable components.

Testing LWC with Jest: Write fast, reliable unit tests for Lightning Web Components with sfdx-lwc-jest: rendering and querying shadow DOM, async timing, mocking Apex, wire adapters, navigation, toasts and modals, accessibility checks with sa11y, coverage in CI, and where UTAM end-to-end tests fit.

LWC Security and Performance: How Lightning Web Security and Lightning Locker sandbox your code, how CSP and Trusted URLs control what you can load, how to avoid XSS and over-exposed Apex, and how to make components fast: LDS caching, cacheable Apex, lazy loading, large lists, debouncing and profiling.

Application Lifecycle Management and DevOps: How Salesforce teams move changes safely from idea to production: development models, sandbox strategy, Metadata API deployments, validation and quick deploy, test levels, destructive changes, DevOps Center, a complete GitHub Actions pipeline with JWT and delta deployments, unlocked and 2GP managed packages, branching, rollback and the DevOps tool landscape.
