+
+## GitHub Actions Best Practices
+
+### 1. Modular Workflow Design
+
+```yaml
+# .github/workflows/ci.yml - Main CI workflow
+name: CI
+
+on:
+  push:
+    branches: [main, develop]
+  pull_request:
+    branches: [main]
+
+# Cancel in-progress runs for same workflow
+concurrency:
+  group: ${{ github.workflow }}-${{ github.ref }}
+  cancel-in-progress: true
+
+jobs:
+  # Call reusable workflows
+  quality:
+    uses: ./.github/workflows/quality-checks.yml
+
+  test:
+    uses: ./.github/workflows/test.yml
+    secrets: inherit
+
+  build:
+    needs: [quality, test]
+    uses: ./.github/workflows/build.yml
+    secrets: inherit
+```
+
+```yaml
+# .github/workflows/quality-checks.yml - Reusable workflow
+name: Quality Checks
+
+on:
+  workflow_call:
+
+jobs:
+  lint:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+
+      - name: Setup Node.js
+        uses: actions/setup-node@v4
+        with:
+          node-version: '20'
+          cache: 'npm'
+
+      - name: Install dependencies
+        run: npm ci
+
+      - name: Run ESLint
+        run: npm run lint -- --format=json --output-file=eslint-report.json

+        with:
+          repo-token: ${{ secrets.GITHUB_TOKEN }}
+          report-json: eslint-report.json
+
+      - name: Check formatting
+        run: npm run format:check
+
+  type-check:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4

+          cache: 'npm'
+
+      - name: Install dependencies
+        run: npm ci
+
+      - name: Type check
+        run: npm run type-check
+
+  security:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+
+      - name: Run npm audit
+        run: npm audit --audit-level=moderate
+
+      - name: Run Snyk
+        uses: snyk/actions/node@master
+        env:
+          SNYK_TOKEN: ${{ secrets.SNYK_TOKEN }}
+```
+
+### 2. Matrix Builds
+
+```yaml
+# Test multiple versions/configurations
+test:
+  name: Test (Node ${{ matrix.node }} on ${{ matrix.os }})
+  runs-on: ${{ matrix.os }}
+  strategy:
+    # Don't cancel other jobs if one fails
+    fail-fast: false
+    matrix:
+      os: [ubuntu-latest, windows-latest, macos-latest]
+      node: [18, 20, 21]
+      # Exclude specific combinations
+      exclude:
+        - os: windows-latest
+          node: 18
+      # Include specific combinations
+      include:
+        - os: ubuntu-latest
+          node: 20
+          coverage: true
+
+  steps:
+    - uses: actions/checkout@v4
+
+    - name: Setup Node.js ${{ matrix.node }}
+      uses: actions/setup-node@v4
+      with:
+        node-version: ${{ matrix.node }}
+        cache: 'npm'
+
+    - name: Install dependencies
+      run: npm ci
+
+    - name: Run tests
+      run: npm test
+      env:
+        NODE_VERSION: ${{ matrix.node }}
+
+    # Only run coverage on one matrix job
+    - name: Upload coverage
+      if: matrix.coverage
+      uses: codecov/codecov-action@v3
+      with:
+        files: ./coverage/coverage-final.json
+```
+
+### 3. Caching Strategies
+
+```yaml
+cache-dependencies:
+  runs-on: ubuntu-latest
+  steps:
+    - uses: actions/checkout@v4
+
+    # Cache npm dependencies
+    - name: Cache node modules
+      uses: actions/cache@v3
+      with:
+        path: |
+          ~/.npm
+          node_modules
+        key: ${{ runner.os }}-node-${{ hashFiles('**/package-lock.json') }}
+        restore-keys: |
+          ${{ runner.os }}-node-
+
+    # Cache build outputs
+    - name: Cache build
+      uses: actions/cache@v3
+      with:
+        path: |
+          .next/cache
+          dist
+        key: ${{ runner.os }}-build-${{ github.sha }}
+        restore-keys: |
+          ${{ runner.os }}-build-
+
+    # Docker layer caching
+    - name: Set up Docker Buildx
+      uses: docker/setup-buildx-action@v3
+
+    - name: Build with cache
+      uses: docker/build-push-action@v5
+      with:
+        context: .
+        cache-from: type=gha
+        cache-to: type=gha,mode=max
+        push: false
+```
+
+### 4. Conditional Execution
+
+```yaml
+deploy:
+  runs-on: ubuntu-latest
+  # Only deploy from main branch
+  if: github.ref == 'refs/heads/main' && github.event_name == 'push'
+
+  steps:
+    - name: Deploy to staging
+      if: contains(github.event.head_commit.message, '[deploy-staging]')
+      run: ./scripts/deploy-staging.sh
+
+    - name: Deploy to production
+      if: startsWith(github.ref, 'refs/tags/v')
+      run: ./scripts/deploy-production.sh
+
+    # Different job based on file changes
+    - uses: dorny/paths-filter@v2
+      id: changes
+      with:
+        filters: |
+          frontend:
+            - 'src/frontend/**'
+          backend:
+            - 'src/backend/**'
+
+    - name: Deploy frontend
+      if: steps.changes.outputs.frontend == 'true'
+      run: ./scripts/deploy-frontend.sh
+
+    - name: Deploy backend
+      if: steps.changes.outputs.backend == 'true'
+      run: ./scripts/deploy-backend.sh
+```
+
+### 5. Custom Actions
+
+```yaml
+# .github/actions/setup-project/action.yml
+name: 'Setup Project'
+description: 'Setup Node.js and install dependencies'
+
+inputs:
+  node-version:
+    description: 'Node.js version to use'
+    required: false
+    default: '20'
+  cache-dependency-path:
+    description: 'Path to lock file'
+    required: false
+    default: '**/package-lock.json'
+
+runs:
+  using: 'composite'
+  steps:
+    - name: Setup Node.js
+      uses: actions/setup-node@v4
+      with:
+        node-version: ${{ inputs.node-version }}
+        cache: 'npm'
+        cache-dependency-path: ${{ inputs.cache-dependency-path }}
+
+    - name: Install dependencies
+      shell: bash
+      run: npm ci
+
+    - name: Verify installation
+      shell: bash
+      run: |
+        node --version
+        npm --version
+```
+
+```yaml
+# Use the custom action
+jobs:
+  build:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+
+      - name: Setup project
+        uses: ./.github/actions/setup-project
+        with:
+          node-version: '20'
+```
+
+## GitLab CI Best Practices
+
+### 1. Template Organization
+
+```yaml
+# .gitlab-ci.yml
+include:
+  - local: '.gitlab/ci/templates/node.yml'
+  - local: '.gitlab/ci/templates/docker.yml'
+  - local: '.gitlab/ci/templates/deploy.yml'
+
+stages:
+  - lint
+  - test
+  - build
+  - deploy
+
+variables:
+  NODE_VERSION: "20"
+  DOCKER_DRIVER: overlay2
+
+# Inherit from templates
+lint:js:
+  extends: .node-lint
+
+test:unit:
+  extends: .node-test
+  coverage: '/All files[^|]*\|[^|]*\s+([\d\.]+)/'
+
+build:docker:
+  extends: .docker-build
+  variables:
+    IMAGE_NAME: $CI_REGISTRY_IMAGE
+
+deploy:staging:
+  extends: .deploy-staging
+  only:
+    - main
+```
+
+```yaml
+# .gitlab/ci/templates/node.yml
+.node-base:
+  image: node:${NODE_VERSION}-alpine
+  cache:
+    key: ${CI_COMMIT_REF_SLUG}
+    paths:
+      - node_modules/
+      - .npm/
+  before_script:
+    - npm ci --cache .npm --prefer-offline
+
+.node-lint:
+  extends: .node-base
+  stage: lint
+  script:
+    - npm run lint
+    - npm run format:check
+
+.node-test:
+  extends: .node-base
+  stage: test
+  script:
+    - npm run test -- --coverage
+  artifacts:
+    when: always
+    reports:
+      junit: junit.xml
+      coverage_report:
+        coverage_format: cobertura
+        path: coverage/cobertura-coverage.xml
+    paths:
+      - coverage/
+    expire_in: 30 days
+```
+
+### 2. Dynamic Child Pipelines
+
+```yaml
+# Generate dynamic pipeline based on changes
+generate-pipeline:
+  stage: .pre
+  script:
+    - ./scripts/generate-pipeline.sh > pipeline.yml
+  artifacts:
+    paths:
+      - pipeline.yml
+
+trigger-pipeline:
+  stage: .pre
+  needs: [generate-pipeline]
+  trigger:
+    include:
+      - artifact: pipeline.yml
+        job: generate-pipeline
+    strategy: depend
+```
+
+### 3. Parallel Jobs with DAG
+
+```yaml
+# Use directed acyclic graph for parallel execution
+lint:
+  stage: lint
+  script: npm run lint
+
+test:unit:
+  stage: test
+  needs: []  # Run immediately, don't wait for lint
+  script: npm run test:unit
+
+test:integration:
+  stage: test
+  needs: []  # Run in parallel with unit tests
+  script: npm run test:integration
+
+build:
+  stage: build
+  needs: [lint, test:unit, test:integration]  # Wait for all tests
+  script: npm run build
+```
+
+## Jenkins Pipeline Best Practices
+
+### 1. Declarative Pipeline
+
+```groovy
+// Jenkinsfile
+pipeline {
+    agent any
+
+    options {
+        buildDiscarder(logRotator(numToKeepStr: '10'))
+        disableConcurrentBuilds()
+        timeout(time: 1, unit: 'HOURS')
+        timestamps()
+    }
+
+    environment {
+        NODE_VERSION = '20'
+        DOCKER_REGISTRY = credentials('docker-registry')
+        SLACK_WEBHOOK = credentials('slack-webhook')
+    }
+
+    parameters {
+        choice(name: 'ENVIRONMENT', choices: ['staging', 'production'], description: 'Deployment environment')
+        booleanParam(name: 'RUN_TESTS', defaultValue: true, description: 'Run tests')
+    }
+
+    stages {
+        stage('Checkout') {
+            steps {
+                checkout scm
+            }
+        }
+
+        stage('Setup') {
+            steps {
+                script {
+                    docker.image("node:${NODE_VERSION}").inside {
+                        sh 'npm ci'
+                    }
+                }
+            }
+        }
+
+        stage('Lint') {
+            when {
+                expression { params.RUN_TESTS }

+                        sh 'npm run lint'
+                    }
+                }
+            }
+        }
+
+        stage('Test') {
+            parallel {
+                stage('Unit Tests') {
+                    steps {
+                        script {
+                            docker.image("node:${NODE_VERSION}").inside {
+                                sh 'npm run test:unit'
+                            }
+                        }
+                    }
+                }
+
+                stage('Integration Tests') {
+                    steps {
+                        script {
+                            docker.image("node:${NODE_VERSION}").inside {
+                                sh 'npm run test:integration'
+                            }
+                        }
+                    }
+                }
+            }
+            post {

+                        sh 'npm run build'
+                    }

+            )
+        }
+    }
+}
+```
+
+## Pipeline Optimization Techniques
+
+### 1. Parallel Execution
+
+```yaml
+# Run independent jobs in parallel
+jobs:
+  lint:
+    # Linting doesn't depend on anything
+
+  test-unit:
+    # Unit tests don't depend on linting
+
+  test-integration:
+    # Integration tests don't depend on unit tests
+
+  build:
+    needs: [lint, test-unit, test-integration]
+    # Build only runs after all previous jobs pass
+```
+
+### 2. Skip Redundant Work
+
+```yaml
+# Only run jobs when relevant files change
+test-frontend:
+  rules:
+    - changes:
+        - src/frontend/**/*
+        - package.json
+
+test-backend:
+  rules:
+    - changes:
+        - src/backend/**/*
+        - requirements.txt
+
+# Skip CI on docs-only changes
+workflow:
+  rules:
+    - if: '$CI_COMMIT_MESSAGE =~ /\[skip ci\]/'
+      when: never
+    - changes:
+        - '**/*.md'
+      when: never
+    - when: always
+```
+
+### 3. Artifacts and Dependencies
+
+```yaml
+build:
+  script:
+    - npm run build
+  artifacts:
+    paths:
+      - dist/
+    expire_in: 1 hour
+
+deploy:
+  needs:
+    - job: build
+      artifacts: true
+  script:
+    - ./deploy.sh dist/
+```
+
+## Security Best Practices
+
+### 1. Secret Management
+
+```yaml
+# ❌ BAD: Hardcoded secrets
+env:
+  DATABASE_URL: postgresql://user:password@localhost/db
+
+# ✅ GOOD: Use secrets
+env:
+  DATABASE_URL: ${{ secrets.DATABASE_URL }}
+
+# ✅ BETTER: Mask secrets in logs
+- name: Use secret
+  run: |
+    echo "::add-mask::${{ secrets.API_KEY }}"
+    ./script.sh --api-key="${{ secrets.API_KEY }}"
+```
+
+### 2. Dependency Scanning
+
+```yaml
+security-scan:
+  steps:
+    - name: Scan dependencies
+      run: npm audit --audit-level=moderate
+
+    - name: Scan with Snyk
+      uses: snyk/actions/node@master
+      env:
