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

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 = 'unknown@example.com';
}
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 WHERE clause
List<Opportunity> opps = [
SELECT Id, Name, Amount, StageName
FROM Opportunity
WHERE AccountId IN :accountIds // indexed field
AND CloseDate >= :Date.today() // indexed field
ORDER BY CloseDate ASC
LIMIT 200
];
// Relationship query to avoid extra round-trips
List<Account> accounts = [
SELECT Id, Name,
(SELECT Id, LastName, Email FROM Contacts WHERE Email != null)
FROM Account
WHERE Id IN :accountIds
