## Development Workflows

### Workflow 1: New Project Setup

```bash
# 1. Scaffold project
python senior-fullstack/scripts/project_scaffolder.py my-app --type nextjs-graphql

# 2. Start services
cd my-app && docker-compose up -d

# 3. Run migrations
npm run migrate

# 4. Start development
npm run dev
```

### Workflow 2: Code Quality Check

```bash
# 1. Analyze codebase
python senior-fullstack/scripts/code_quality_analyzer.py ./

# 2. Fix security issues
npm audit fix

# 3. Run tests
npm test

# 4. Build production
npm run build
```

### Workflow 3: ML Model Deployment

```bash
# 1. Setup MLOps infrastructure
python senior-ml-engineer/scripts/mlops_setup_tool.py

# 2. Deploy model
python senior-ml-engineer/scripts/model_deployment_pipeline.py model.pkl

# 3. Monitor performance
# Check MLflow dashboard
```

## Quality Standards

**All engineering tools must:**
- Support modern tech stacks (Next.js, React, Vue, Express)
- Generate production-ready code
- Include testing infrastructure
- Provide Docker configurations
- Support CI/CD integration

## Integration Patterns

### GitHub Actions CI/CD

All scaffolders generate GitHub Actions workflows:
```yaml
.github/workflows/
├── test.yml          # Run tests on PR
├── build.yml         # Build and lint
└── deploy.yml        # Deploy to production
```

### Docker Compose

Multi-service development environment:
```yaml
services:
  - app (Next.js)
  - api (GraphQL)
  - db (PostgreSQL)
  - redis (Cache)
```
