## About

# Senior Fullstack

Guide fullstack development using modern tools and established patterns.

## Core Workflow

### 1. Scaffold a Project

Run the fullstack scaffolder to generate project structure:

```bash
python scripts/fullstack_scaffolder.py  [options]
```

Use the project scaffolder for analysis and optimization:

```bash
python scripts/project_scaffolder.py  [--verbose]
```

### 2. Analyze Code Quality

Run the analyzer to detect issues and get recommendations:

```bash
python scripts/code_quality_analyzer.py [--analyze]
```

### 3. Apply Architecture Patterns

Consult reference docs before implementing:

- `references/tech_stack_guide.md` -- patterns, examples, anti-patterns
- `references/architecture_patterns.md` -- workflows, optimization, troubleshooting
- `references/development_workflows.md` -- integrations, security, scalability

## Tech Stack

| Layer | Technologies |
|-------|-------------|
| Languages | TypeScript, JavaScript, Python, Go |
| Frontend | React, Next.js, React Native |
| Backend | Node.js, Express, GraphQL, REST |
| Database | PostgreSQL, Prisma, Supabase |
| DevOps | Docker, Kubernetes, Terraform, GitHub Actions |
| Cloud | AWS, GCP, Azure |

## Key Principles

- **Immutability**: Return new objects, never mutate (`{ ...obj, key: value }`)
- **Validation**: Use Zod for input validation, parameterized queries for SQL
- **Structure**: Functions under 50 lines, files under 800 lines, nesting under 4 levels
- **Security**: No hardcoded secrets, server-side API calls only, proper auth checks

## Common Commands

```bash
npm run dev          # Start dev server
npm run build        # Production build
npm test             # Run tests
npm run lint         # Lint code
docker build -t app:latest .   # Build container
```

## Error Handling

- If scaffolder fails: verify Python 3.8+ is installed and scripts/ directory exists
- If quality analyzer reports issues: fix CRITICAL/HIGH first, then MEDIUM
- If build fails after scaffolding: check `package.json` dependencies and `.env` configuration
- Always run `npm run type-check` before committing changes
