# Salesforce Developer

## Core Workflow

1. **Analyze requirements** - Understand business needs, data model, governor limits, scalability
2. **Design solution** - Choose declarative vs programmatic, plan bulkification, design integrations
3. **Implement** - Write Apex classes, LWC components, SOQL queries with best practices
4. **Validate governor limits** - Verify SOQL/DML counts, heap size, and CPU time stay within platform limits before proceeding
5. **Test thoroughly** - Write test classes with 90%+ coverage, test bulk scenarios (200-record batches)
6. **Deploy** - Use Salesforce DX, scratch orgs, CI/CD for metadata deployment

## Reference Guide

Load detailed guidance based on context:

| Topic | Reference | Load When |
|-------|-----------|-----------|
| Apex Development | `references/apex-development.md` | Classes, triggers, async patterns, batch processing |
| Lightning Web Components | `references/lightning-web-components.md` | LWC framework, component design, events, wire service |
| SOQL/SOSL | `references/soql-sosl.md` | Query optimization, relationships, governor limits |
| Integration Patterns | `references/integration-patterns.md` | REST/SOAP APIs, platform events, external services |
| Deployment & DevOps | `references/deployment-devops.md` | Salesforce DX, CI/CD, scratch orgs, metadata API |

## Constraints

### MUST DO
- Bulkify Apex code — collect IDs/records before loops, query/DML outside loops
- Write test classes with minimum 90% code coverage, including bulk scenarios
- Use selective SOQL queries with indexed fields; leverage relationship queries
- Use appropriate async processing (batch, queueable, future) for long-running work
- Implement proper error handling and logging; use `Database.update(scope, false)` for partial success
- Use Salesforce DX for source-driven development and metadata deployment

### MUST NOT DO
- Execute SOQL/DML inside loops (governor limit violation — see bulkified trigger pattern below)
- Hard-code IDs or credentials in code
- Create recursive triggers without safeguards
- Skip field-level security and sharing rules checks
- Use deprecated Salesforce APIs or components

## Code Patterns

### Bulkified Trigger (Correct Pattern)

```apex
// CORRECT: collect IDs, query once outside the loop
trigger AccountTrigger on Account (before insert, before update) {
    AccountTriggerHandler.handleBeforeInsert(Trigger.new);
}

public class AccountTriggerHandler {
    public static void handleBeforeInsert(List<Account> newAccounts) {
        Set<Id> parentIds = new Set<Id>();
        for (Account acc : newAccounts) {
            if (acc.ParentId != null) parentIds.add(acc.ParentId);
        }
        Map<Id, Account> parentMap = new Map<Id, Account>(
            [SELECT Id, Name FROM Account WHERE Id IN :parentIds]
        );
        for (Account acc : newAccounts) {
            if (acc.ParentId != null && parentMap.containsKey(acc.ParentId)) {
                acc.Description = 'Child of: ' + parentMap.get(acc.ParentId).Name;
            }
        }
    }
}
```

```apex
// INCORRECT: SOQL inside loop — governor limit violation
trigger AccountTrigger on Account (before insert) {
    for (Account acc : Trigger.new) {
        Account parent = [SELECT Id, Name FROM Account WHERE Id = :acc.ParentId]; // BAD
        acc.Description = 'Child of: ' + parent.Name;
    }
}
```

### Batch Apex

```apex
public class ContactBatchUpdate implements Database.Batchable<SObject> {
    public Database.QueryLocator start(Database.BatchableContext bc) {
        return Database.getQueryLocator([SELECT Id, Email FROM Contact WHERE Email = null]);
    }
    public void execute(Database.BatchableContext bc, List<Contact> scope) {
        for (Contact c : scope) {
            c.Email = '[email protected]';
        }
        Database.update(scope, false); // partial success allowed
    }
    public void finish(Database.BatchableContext bc) {
        // Send notification or chain next batch
    }
}
// Execute: Database.executeBatch(new ContactBatchUpdate(), 200);
```

### Test Class

```apex
@IsTest
private class AccountTriggerHandlerTest {
    @TestSetup
    static void makeData() {
        Account parent = new Account(Name = 'Parent Co');
        insert parent;
        Account child = new Account(Name = 'Child Co', ParentId = parent.Id);
        insert child;
    }

    @IsTest
    static void testBulkInsert() {
        Account parent = [SELECT Id FROM Account WHERE Name = 'Parent Co' LIMIT 1];
        List<Account> children = new List<Account>();
        for (Integer i = 0; i < 200; i++) {
            children.add(new Account(Name = 'Child ' + i, ParentId = parent.Id));
        }
        Test.startTest();
        insert children;
        Test.stopTest();

        List<Account> updated = [SELECT Description FROM Account WHERE ParentId = :parent.Id];
        System.assert(!updated.isEmpty(), 'Children should have descriptions set');
        System.assert(updated[0].Description.startsWith('Child of:'), 'Description format mismatch');
    }
}
```

### SOQL Best Practices

```apex
// Selective query — use indexed fields in WHE
