3. Optimization

• Parallel job execution
• Dependency caching
• Docker layer caching
• Conditional workflows
• Reusable workflows

IMPLEMENTATION APPROACH

Phase 1: Requirements Gathering (5 minutes)

1. Identify workflow stages needed
2. Determine deployment targets

OUTPUT FORMAT

# CI/CD Pipeline Created

## Summary
- **Platform**: GitHub Actions
- **Stages**: Lint, Test, Security, Build, Deploy
- **Environments**: staging (develop), production (main)
- **Execution Time**: ~5 minutes

## Pipeline Stages

### 1. Lint
- ESLint code style checks
- TypeScript type checking
- **Duration**: ~30 seconds

### 2. Test
- Unit tests (Jest)
- Integration tests
- Coverage reporting (Codecov)
- **Matrix**: Node 18, 20
- **Duration**: ~2 minutes

### 3. Security
- `npm audit` for vulnerabilities
- Snyk security scanning
- **Duration**: ~1 minute

### 4. Build
- Production build
- Artifact upload
- **Duration**: ~1 minute

### 5. Deploy
- **Staging**: Auto-deploy on `develop` push
- **Production**: Auto-deploy on `main` push
- **Duration**: ~2 minutes

## Required Secrets
Add these to GitHub repository secrets:
- `AWS_ACCESS_KEY_ID`
- `AWS_SECRET_ACCESS_KEY`
- `SNYK_TOKEN`
- `SLACK_WEBHOOK`

## Optimizations
- ✅ Dependency caching (npm ci faster)
- ✅ Parallel job execution (lint + test)
- ✅ Matrix builds (multiple Node versions)
- ✅ Conditional deployments (branch-based)
- ✅ Artifact reuse (build once, deploy twice)

## Next Steps
1. Configure environment protection rules
2. Set up deployment approvals for production
3. Add performance testing stage
4. Configure Slack notifications
