Certification Roadmap & Career Strategy

1// Skills Assessment — Self-Evaluation Code Challenges
2
3// LEVEL 1: Developer Fundamentals
4// Can you write this from memory?
5
6// Challenge: Bulkified trigger with test class
7public class AccountTriggerHandlerTest {
8    
9    @TestSetup
10    static void setup() {
11        List<Account> accounts = new List<Account>();
12        for (Integer i = 0; i < 200; i++) {
13            accounts.add(new Account(Name = 'Test Account ' + i));
14        }
15        insert accounts;
16    }
17    
18    @isTest
19    static void testBulkInsert() {
20        List<Contact> contacts = new List<Contact>();
21        List<Account> accounts = [SELECT Id FROM Account];
22        
23        for (Account acc : accounts) {
24            contacts.add(new Contact(
25                FirstName = 'Test',
26                LastName = 'Contact',
27                AccountId = acc.Id
28            ));
29        }
30        
31        Test.startTest();
32        insert contacts; // Should not hit governor limits
33        Test.stopTest();
34        
35        System.assertEquals(200, [SELECT COUNT() FROM Contact]);
36    }
37}
38
39// LEVEL 2: Senior Developer
40// Can you explain and implement these patterns?
41
42// Trigger Framework + Service Layer + Error Handling
43// (See Phase 3b and Phase 9 for full implementations)
44
45// LEVEL 3: Architect
46// Can you design this on a whiteboard?
47
48// Challenge: Design a real-time notification system
49// Requirements:
50// - 10,000 users
51// - Notifications for: deal approvals, SLA breaches, territory changes
52// - Multi-channel: in-app, email, mobile push
53// - Configurable per user (opt-in/opt-out)
54// - Audit trail for all notifications
55
56// Architecture sketch:
57// 1. Notification_Template__c — configurable templates
58// 2. User_Notification_Pref__c — per-user channel preferences
59// 3. Platform Event: Notification_Event__e — published by triggers/flows
60// 4. Event subscriber trigger → routes to channels:
61//    a. In-app: Custom Notification API
62//    b. Email: Messaging.SingleEmailMessage
63//    c. Mobile push: Firebase via Named Credential callout
64// 5. Notification_Log__c — audit trail
65// 6. LWC component: empApi subscriber for real-time in-app display
66// 7. Notification dashboard: read/unread counts, history
