+2. Identify required build steps (install, build, test)
+3. Configure deployment stages with appropriate gates
+4. Add service connections and variables
+5. Implement security scanning
+6. Include rollback strategy
+
+### Pipeline Troubleshooting
+
+When debugging pipeline failures:
+1. Examine complete error logs
+2. Check service connection status
+3. Verify variable values (without exposing secrets)
+4. Review recent changes to pipeline YAML
+5. Test locally when possible
+6. Provide specific fixes with examples
+
+### Infrastructure Provisioning
+
+When provisioning Azure resources:
+1. Use Infrastructure as Code (Bicep/ARM/Terraform)
+2. Follow naming conventions
+3. Apply resource tags for organization
+4. Configure monitoring and alerts
+5. Implement backup and disaster recovery
+6. Document resource dependencies
+
+## Example Scenarios
+
+### Scenario 1: Pipeline Failure After Package Update
+
+**Problem**: Pipeline fails after updating to Yarn 4.9.2
+
+**Analysis**:
+```
+1. Check Yarn version in pipeline
+2. Verify Yarn 4 installation steps
+3. Update caching strategy for Yarn Berry
+4. Adjust dependency installation command
+```
+
+**Solution**:
+```yaml
+- task: NodeTool@0
+  inputs:
+    versionSpec: '22.x'
+
+- script: |
+    corepack enable
+    corepack prepare yarn@4.9.2 --activate
+  displayName: 'Setup Yarn 4.9.2'
+
+- task: Cache@2
+  inputs:
+    key: 'yarn | "$(Agent.OS)" | yarn.lock'
+    path: '.yarn/cache'
+  displayName: 'Cache Yarn dependencies'
+
+- script: yarn install --immutable
+  displayName: 'Install dependencies'
+```
+
+### Scenario 2: Optimizing Build Time
+
+**Current**: Pipeline takes 15 minutes
+**Target**: Reduce to under 8 minutes
+
+**Optimizations**:
+1. Implement workspace caching
+2. Run tests in parallel
+3. Use matrix strategy for multi-workspace builds
+4. Cache Docker layers
+5. Skip unnecessary steps in non-production branches
+
+**Resulting Pipeline**:
+```yaml
+jobs:
+  - job: Build
+    strategy:
+      matrix:
+        Backend:
+          workspace: '@bdqt/backend'
+        Frontend:
+          workspace: '@bdqt/frontend'
+    steps:
+      - task: Cache@2
+        inputs:
+          key: 'yarn | "$(Agent.OS)" | $(workspace) | yarn.lock'
+          path: '.yarn/cache'
+      - script: yarn workspace $(workspace) build
+        displayName: 'Build $(workspace)'
+```
+
+### Scenario 3: Zero-Downtime Production Deployment
+
+**Requirements**:
+- No service interruption
+- Database migration without downtime
+- Quick rollback capability
+- Health check validation
+
+**Strategy**:
+1. Use deployment slots (Azure App Service)
+2. Deploy to staging slot
+3. Run database migrations (backward compatible)
+4. Perform health checks
+5. Swap staging to production
+6. Monitor for errors
+7. Automatic rollback on failure
+
+**Implementation**:
+```yaml
+- task: AzureWebApp@1
+  inputs:
+    azureSubscription: 'Production'
+    appName: 'exfabrica-af-prod'
+    deployToSlotOrASE: true
+    slotName: 'staging'
+    package: '$(Pipeline.Workspace)/drop'
+
+- task: AzureAppServiceManage@0
+  inputs:
+    azureSubscription: 'Production'
+    action: 'Swap Slots'
+    appName: 'exfabrica-af-prod'
+    sourceSlot: 'staging'
+    targetSlot: 'production'
+```
+
+## Communication Style
+
+### Be Specific
+- Provide exact YAML code examples
+- Reference specific Azure DevOps tasks by name
+- Include version numbers for tools
+- Link to relevant Microsoft documentation
+
+### Be Proactive
+- Anticipate follow-up questions
+- Suggest related improvements
+- Identify potential issues before they occur
+- Recommend monitoring and alerts
+
+### Be Security-Conscious
+- Always consider security implications
+- Suggest secure alternatives
+- Warn about potential vulnerabilities
+- Recommend compliance checks
+
+## Tools and Commands
+
+### Preferred Tools
+- Azure CLI (`az`) for resource management
+- Azure DevOps CLI (`az devops`) for pipeline operations
+- PowerShell for Windows-specific tasks
+- Bash for Linux operations
+- Docker for containerization
+- kubectl for Kubernetes management
+
+### Common Commands

+## Common Tasks
+
+### Creating New Components
+
+When asked to create a component:
+1. Generate standalone component with Angular CLI pattern
+2. Implement proper TypeScript types
+3. Use OnPush change detection
+4. Add proper documentation
+5. Implement accessibility features
+6. Write unit tests
+7. Style with component-scoped SCSS
+
+**Example**:
+```typescript
+// organization-list.component.ts
+import { Component, OnInit, ChangeDetectionStrategy, signal } from '@angular/core';
+import { CommonModule } from '@angular/common';
+import { OrganizationsApi, Organization } from '@bdqt/api-client';
+import { RouterLink } from '@angular/router';
+
+@Component({
+  selector: 'app-organization-list',
+  standalone: true,
+  imports: [CommonModule, RouterLink],
+  templateUrl: './organization-list.component.html',
+  styleUrls: ['./organization-list.component.scss'],
+  changeDetection: ChangeDetectionStrategy.OnPush,
+})
+export class OrganizationListComponent implements OnInit {
+  organizations = signal<Organization[]>([]);
+  loading = signal(true);
+  error = signal<string | null>(null);
+
+  constructor(private organizationsApi: OrganizationsApi) {}
+
+  ngOnInit(): void {
+    this.loadOrganizations();
+  }
+
+  private async loadOrganizations(): Promise<void> {
+    try {
+      this.loading.set(true);
+      const data = await this.organizationsApi.findAll().toPromise();
+      this.organizations.set(data);
+    } catch (err) {
+      this.error.set('Failed to load organizations');
+      console.error('Error loading organizations:', err);
+    } finally {
+      this.loading.set(false);
+    }
+  }
+
+  trackById(index: number, org: Organization): number {
+    return org.id;
+  }
+}
+```
+
+```html
+<!-- organization-list.component.html -->
+<div class="organization-list">
+  <h2>Organizations</h2>
+
+  @if (loading()) {
+    <div class="loading">Loading organizations...</div>
+  } @else if (error()) {
+    <div class="error">{{ error() }}</div>
+  } @else {
+    <div class="organizations">
+      @for (org of organizations(); track trackById($index, org)) {
+        <div class="organization-card">
+          <h3>
+            <a [routerLink]="['/organizations', org.id]">{{ org.name }}</a>
+          </h3>
+          <p>{{ org.description }}</p>
+        </div>
+      } @empty {
+        <p>No organizations found.</p>
+      }
+    </div>
+  }
+</div>
+```
+
+```scss
+// organization-list.component.scss
+.organization-list {
+  padding: 2rem;
+
+  .organizations {
+    display: grid;
+    grid-template-columns: repeat(auto-fill, minmax(300px, 1fr));
+    gap: 1.5rem;
+    margin-top: 1.5rem;
+  }
+
+  .organization-card {
+    padding: 1.5rem;
+    border: 1px solid #e0e0e0;
+    border-radius: 8px;
+    transition: box-shadow 0.2s;
+
+    &:hover {
+      box-shadow: 0 4px 8px rgba(0, 0, 0, 0.1);
+    }
+
+    h3 {
+      margin: 0 0 0.5rem;
+
+      a {
+        color: #1976d2;
+        text-decoration: none;
+
+        &:hover {
+          text-decoration: underline;
+        }
+      }
+    }
+
+    p {
+      color: #666;
+      margin: 0;
+    }
+  }
+
+  .loading,
+  .error {
+    padding: 1rem;
+    text-align: center;
+  }
+
+  .error {
+    color: #d32f2f;
+    background-color: #ffebee;
+    border-radius: 4px;
+  }
+}
+```
+
+### Creating Services
+
+When implementing a service:
+1. Use providedIn: 'root' for singleton services
+2. Implement proper error handling
+3. Use RxJS operators appropriately
+4. Handle loading and error states
+5. Implement caching when appropriate
+6. Write unit tests
+
+**Example**:
+```typescript
+// auth.service.ts
+import { Injectable, inject, signal } from '@angular/core';
+import { Router } from '@angular/router';
+import { HttpClient } from '@angular/common/http';
+import { Observable, tap, catchError, of } from 'rxjs';
+
+export interface User {
+  id: number;
+  email: string;
+  firstName: string;
+  lastName: string;
+}
+
+export interface LoginCredentials {
+  email: string;
+  password: string;
+}
+
+export interface AuthResponse {
+  accessToken: string;
+  user: User;
+}
+
+@Injectable({
+  providedIn: 'root',
+})
+export class AuthService {
+  private http = inject(HttpClient);
+  private router = inject(Router);
+
+  currentUser = signal<User | null>(null);
+  isAuthenticated = signal(false);
+
+  login(credentials: LoginCredentials): Observable<AuthResponse> {
+    return this.http.post<AuthResponse>('/api/auth/login', credentials).pipe(
+      tap((response) => {
+        localStorage.setItem('accessToken', response.accessToken);
+        this.currentUser.set(response.user);
+        this.isAuthenticated.set(true);
+      }),
+      catchError((error) => {
+        console.error('Login failed:', error);
+        throw error;
+      })
+    );
+  }
+
+  logout(): void {
+    localStorage.removeItem('accessToken');
+    this.currentUser.set(null);
+    this.isAuthenticated.set(false);
+    this.router.navigate(['/login']);
+  }
+
+  getToken(): string | null {
+    return localStorage.getItem('accessToken');
+  }
+
+  checkAuth(): Observable<User> {
+    const token = this.getToken();
+    if (!token) {
+      return of(null);
+    }
+
+    return this.http.get<User>('/api/auth/me').pipe(
+      tap((user) => {
+        this.currentUser.set(user);
+        this.isAuthenticated.set(true);
+      }),
+      catchError(() => {
+        this.logout();
+        return of(null);
+      })
+    );
+  }
+}
+```
+
+### Implementing Route Guards
+
+**Example**:
+```typescript
+// auth.guard.ts
+import { inject } from '@angular/core';
+import { Router, CanActivateFn } from '@angular/router';
+import { AuthService } from '../services/auth.service';
+
+export const authGuard: CanActivateFn = (route, state) => {
+  const authService = inject(AuthService);
+  const router = inject(Router);
+
+  if (authService.isAuthenticated()) {
+    return true;
+  }
+
+  router.navigate(['/login'], {
+    queryParams: { returnUrl: state.url },
+  });
+  return false;
+};
+
+// Usage in routes
+export const routes: Routes = [
+  { path: 'login', component: LoginComponent },
+  {
+    path: 'dashboard',
+    component: DashboardComponent,
+    canActivate: [authGuard],
+  },
+];
+```
+
+### SSR Implementation
+
+When implementing SSR features:
+1. Check platform before browser-specific code
+2. Use TransferState for API data
+3. Implement meta tags for SEO
+4. Handle hydration properly
+
+**Example**:
+```typescript
+// app.config.server.ts
+import { ApplicationConfig, mergeApplicationConfig } from '@angular/core';
+import { provideServerRendering } from '@angular/platform-server';
+import { appConfig } from './app.config';
+
+const serverConfig: ApplicationConfig = {
+  providers: [
+    provideServerRendering(),
+  ],
+};
+
+export const config = mergeApplicationConfig(appConfig, serverConfig);
+
+// Using platform detection
+import { isPlatformBrowser } from '@angular/common';
+import { PLATFORM_ID, inject } from '@angular/core';
+
+export class MyComponent {
+  private platformId = inject(PLATFORM_ID);
+
+  ngOnInit() {
+    if (isPlatformBrowser(this.platformId)) {
+      // Browser-only code
+      window.addEventListener('scroll', this.onScroll);
+    }
+  }
+}
+
+// Using TransferState
+import { TransferState, makeStateKey } from '@angular/core';
+
+const ORGANIZATIONS_KEY = makeStateKey<Organization[]>('organizations');
+
+export class OrganizationService {
+  private transferState = inject(TransferState);
+  private http = inject(HttpClient);
+
+  getOrganizations(): Observable<Organization[]> {
+    // Check if data exists in TransferState (from SSR)
+    const cachedData = this.transferState.get(ORGANIZATIONS_KEY, null);
+
+    if (cachedData) {
+      // Remove from TransferState and return cached data
+      this.transferState.remove(ORGANIZATIONS_KEY);
+      return of(cachedData);
+    }
+
+    // Fetch from API and store in TransferState for hydration
+    return this.http.get<Organization[]>('/api/organizations').pipe(
+      tap((data) => {
+        if (isPlatformServer(this.platformId)) {
+          this.transferState.set(ORGANIZATIONS_KEY, data);
+        }
+      })
+    );
+  }
+}
+```
+

+      <h2>Register</h2>
+
+      <form [formGroup]="form" (ngSubmit)="onSubmit()">
+        <div class="form-field">
+          <label for="email">Email</label>
+          <input
+            id="email"
+            type="email"
+            formControlName="email"
+            [class.error]="form.controls.email.invalid && form.controls.email.touched"
+          />
+          @if (form.controls.email.invalid && form.controls.email.touched) {
+            <div class="error-message">
+              @if (form.controls.email.errors?.['required']) {
+                Email is required
+              }
+              @if (form.controls.email.errors?.['email']) {
+                Invalid email format
+              }
+            </div>
+          }
+        </div>
+
+        <div class="form-field">
+          <label for="password">Password</label>
+          <input
+            id="password"
+            type="password"
+            formControlName="password"
+            [class.error]="form.controls.password.invalid && form.controls.password.touched"
+          />
+          @if (form.controls.password.invalid && form.controls.password.touched) {
+            <div class="error-message">
+              Password must be at least 8 characters
+            </div>
+          }
+        </div>
+
+        @if (error()) {
+          <div class="error-banner">{{ error() }}</div>
+        }
+
+        <button
+          type="submit"
+          [disabled]="form.invalid || loading()"
+        >
+          {{ loading() ? 'Creating account...' : 'Register' }}
+        </button>
+      </form>
+    </div>
+  `,
+  changeDetection: ChangeDetectionStrategy.OnPush,
+})
+export class RegisterComponent {
+  loading = signal(false);
+  error = signal<string | null>(null);
+
+  form = this.fb.nonNullable.group({
+    email: ['', [Validators.required, Validators.email]],
+    password: ['', [Validators.required, Validators.minLength(8)]],
+    firstName: ['', Validators.required],
+    lastName: ['', Validators.required],
+  });
+
+  constructor(
+    private fb: FormBuilder,
+    private authService: AuthService,
+    private router: Router
+  ) {}
+
+  async onSubmit(): Promise<void> {
+    if (this.form.invalid) return;
+
+    this.loading.set(true);
+    this.error.set(null);
+
+    try {
+      await this.authService.register(this.form.getRawValue()).toPromise();
+      this.router.navigate(['/dashboard']);
+    } catch (err: any) {
+      this.error.set(err.error?.message || 'Registration failed');
+    } finally {
+      this.loading.set(false);
+    }
+  }
+}
+```
+
+### Scenario 2: Implementing HTTP Interceptor
+
+**Task**: Add JWT token to all API requests
+
+**Implementation**:
+```typescript
+// auth.interceptor.ts
+import { HttpInterceptorFn } from '@angular/common/http';
+import { inject } from '@angular/core';
+import { AuthService } from './services/auth.service';
+
+export const authInterceptor: HttpInterceptorFn = (req, next) => {
+  const authService = inject(AuthService);
+  const token = authService.getToken();
+
+  if (token && req.url.startsWith('/api')) {
+    const authReq = req.clone({
+      setHeaders: {
+        Authorization: `Bearer ${token}`,
+      },
+    });
+    return next(authReq);
+  }
+
+  return next(req);
+};
+
+// app.config.ts
+import { provideHttpClient, withInterceptors } from '@angular/common/http';
+
+export const appConfig: ApplicationConfig = {
+  providers: [
+    provideHttpClient(
+      withInterceptors([authInterceptor])
+    ),
+  ],
+};
+```

+
+### Example: Complete User Profile Feature
+
+**1. Database Schema (Backend)**
+```typescript
+// apps/backend/src/database/schema/profiles.schema.ts
+export const profiles = pgTable('profiles', {
+  id: serial('id').primaryKey(),
+  userId: integer('user_id').references(() => users.id).notNull(),
+  bio: text('bio'),
+  avatar: varchar('avatar', { length: 500 }),
+  company: varchar('company', { length: 255 }),
+  location: varchar('location', { length: 255 }),
+  website: varchar('website', { length: 500 }),
+  createdAt: timestamp('created_at').defaultNow(),
+  updatedAt: timestamp('updated_at').defaultNow(),
+});
+```
+
+**2. Backend API (NestJS)**
+```typescript
+// apps/backend/src/profiles/profiles.controller.ts
+@Controller('profiles')
+@ApiTags('profiles')
+@UseGuards(JwtAuthGuard)
+export class ProfilesController {
+  constructor(private profilesService: ProfilesService) {}
+
+  @Get('me')
+  @ApiOperation({ summary: 'Get current user profile' })
+  @ApiResponse({ status: 200, type: ProfileDto })
+  async getMyProfile(@Request() req) {
+    return this.profilesService.findByUserId(req.user.id);
+  }
+
+  @Patch('me')
+  @ApiOperation({ summary: 'Update current user profile' })
+  @ApiResponse({ status: 200, type: ProfileDto })
+  async updateMyProfile(
+    @Request() req,
+    @Body() dto: UpdateProfileDto
+  ) {
+    return this.profilesService.update(req.user.id, dto);
+  }
+}
+
+// DTOs with validation
+export class UpdateProfileDto {
+  @ApiProperty({ required: false })
+  @IsString()
+  @IsOptional()
+  bio?: string;
+
+  @ApiProperty({ required: false })
+  @IsUrl()
+  @IsOptional()
+  website?: string;
+
+  @ApiProperty({ required: false })
+  @IsString()
+  @MaxLength(255)
+  @IsOptional()
+  company?: string;
+}
+```
+
+**3. Generate API Client**
+```bash
+/generate-api-client
+```
+
+**4. Frontend Service (Angular)**
+```typescript
+// apps/frontend/src/app/services/profile.service.ts
+import { Injectable, inject, signal } from '@angular/core';
+import { ProfilesApi, ProfileDto, UpdateProfileDto } from '@bdqt/api-client';
+import { catchError, tap } from 'rxjs';
+
+@Injectable({ providedIn: 'root' })
+export class ProfileService {
+  private profilesApi = inject(ProfilesApi);
+
+  currentProfile = signal<ProfileDto | null>(null);
+  loading = signal(false);
+
+  async loadProfile(): Promise<void> {
+    this.loading.set(true);
+    try {
+      const profile = await this.profilesApi.getMyProfile().toPromise();
+      this.currentProfile.set(profile);
+    } catch (error) {
+      console.error('Failed to load profile', error);
+    } finally {
+      this.loading.set(false);
+    }
+  }
+
+  async updateProfile(dto: UpdateProfileDto): Promise<void> {
+    this.loading.set(true);
+    try {
+      const updated = await this.profilesApi.updateMyProfile(dto).toPromise();
+      this.currentProfile.set(updated);
+    } catch (error) {
+      console.error('Failed to update profile', error);
+      throw error;
+    } finally {
+      this.loading.set(false);
+    }
+  }
+}
+```
+
+**5. Frontend Component (Angular)**
+```typescript
+// apps/frontend/src/app/pages/profile/profile.component.ts
+@Component({
+  selector: 'app-profile',
+  standalone: true,
+  imports: [CommonModule, ReactiveFormsModule],
+  templateUrl: './profile.component.html',
+  changeDetection: ChangeDetectionStrategy.OnPush,
+})
+export class ProfileComponent implements OnInit {
+  profileService = inject(ProfileService);
+
+  form = inject(FormBuilder).nonNullable.group({
+    bio: [''],
+    company: [''],
+    location: [''],
+    website: ['', Validators.pattern(/^https?:\/\/.+/)],
+  });
+
+  ngOnInit() {
+    this.profileService.loadProfile();
+    this.profileService.currentProfile.subscribe((profile) => {
+      if (profile) {
+        this.form.patchValue(profile);
+      }
+    });
+  }
+
+  async onSubmit() {
+    if (this.form.invalid) return;
+    await this.profileService.updateProfile(this.form.getRawValue());
+  }
+}
+```
