Salesforce Platform Developer II (PD2) Training

Curriculum (PD2-Aligned)

Module 1: Advanced Apex & OOP Patterns

• Design patterns (Strategy, Factory, Unit of Work) in Apex
• Bulkification, limits, governor-friendly design
• Error handling and custom exception strategy
• Security review considerations (CRUD/FLS/Sharing)

Lab: Refactor legacy trigger logic using Service + Selector + UOW pattern.

Module 2: Asynchronous Apex & Transactions

• Future vs Queueable vs Batch vs Schedulable—when & why
• Chaining, partial failures, retry & idempotency
• Platform Events & Change Data Capture
• Transaction boundaries & savepoints

Lab: Build a batch process with robust error and retry handling.

Module 3: Lightning Web Components (LWC) at Scale

• State management, composition, and pub/sub
• Wire adapters vs imperative Apex, caching, offline
• Testing LWCs (Jest) & performance tuning
• UX patterns and accessibility

Lab: Build a multi-step wizard with Apex back-end and Jest tests.

Module 4: Integrations & APIs

• REST/SOAP callouts, Named Credentials, OAuth
• External Services, Platform Events, event-driven patterns
• Callout testing with HTTP mock & retries
• Security: encryption, secrets, compliance

Lab: Build a resilient integration with circuit-breaker style retries.

Module 5: Testing, Debugging & Deployment

• Test strategy: unit, integration, data factories
• CI/CD pipelines (SFDX), static analysis, code coverage
• Performance profiling & log analysis
• Packaging & security review readiness

Lab: Set up SFDX project with tests, PMD checks, and GitHub Actions.

PD2 Topic Plan (12 Sessions · 2h each)

• Session 1 – Apex Architecture & Patterns: Layered services, Selector pattern, UoW, DI, governor-friendly design.
• Session 2 – Triggers & Transactions: Trigger framework, recursion guards, savepoints/rollbacks, mixed DML avoidance.
• Session 3 – Security & Sharing: CRUD/FLS/sharing checks, with/without sharing, stripInaccessible, review gotchas.
• Session 4 – Asynchronous Apex I: Future/Queueable/Batch/Schedulable; chaining, state, error handling.
• Session 5 – Asynchronous Apex II: Platform Events, CDC, event-driven designs, retry & idempotency patterns.
• Session 6 – SOQL/SOSL & Data Modeling: Selectivity, indexes, relationship queries, large-data patterns, locking.
• Session 7 – Integrations I (Callouts): REST/SOAP, Named Credentials, OAuth, mocks, timeouts, circuit-breaker retries.
• Session 8 – Integrations II (Inbound/External): Apex REST, External Services, PE bridges, bulk & async ingestion.
• Session 9 – LWC at Scale: Architecture, composition, state mgmt, wire vs imperative, caching, Jest, perf & a11y.
• Session 10 – Testing Strategy: Data factories/setup, mocking callouts/events, coverage vs quality, flaky fixes.
• Session 11 – Observability & Performance: Debug logs, limits analysis, profiling, bulk/batch tuning.
• Session 12 – Packaging & DevOps: SFDX/CI, PMD, unlocked/managed packaging, security review; mock exam.

Assignments & Project Work

• Trigger refactor: Convert legacy trigger to Service + Selector + UoW with recursion guard.
• Async pipeline: Queueable chain with exponential backoff and idempotency keys.
• Integration lab: Callout client with Named Credentials + mock tests + retry policy.
• LWC wizard: Multi-step component using wire & imperative Apex + Jest tests.
• Test factory pack: Reusable factories and assertions for a mini domain.
