# Find process using port 3000/3001
lsof -i :3000
kill -9 <PID>
```

### Database connection failed
```bash
# Reset database
pnpm db:reset
# Re-seed
pnpm db:seed
```

### Tests failing
```bash
# Clear cache
rm -rf .turbo
# Reinstall
pnpm install
# Run again
pnpm test
```

### Docker issues
```bash
# Complete reset
docker-compose down -v
docker-compose up --build
```

## 🎓 LEARNING PATHS

### Backend Development
1. Read: `docs/architecture.md`
2. Explore: `apps/api/src/modules/auth` (simplest module)
3. Understand: DDD layers (presentation → application → domain → infrastructure)
4. Practice: Add a new endpoint following the pattern

### Frontend Development
1. Review: `apps/web/app` (route structure)
2. Study: `components/listings` (complex component)
3. Learn: React Query patterns in `lib/*-api.ts`
4. Practice: Create a new feature page

### DevOps
1. Review: `docker-compose.yml` (architecture)
2. Study: `.github/workflows` (CI/CD)
3. Learn: `docs/deployment.md` (production)
4. Practice: Deploy to staging environment

---

## 💡 PRO TIPS

- Use `pnpm dev` (from root) to develop all apps simultaneously
- ESLint is configured to catch module boundary violations
- Prisma Studio (`pnpm db:studio`) is great for exploring data
- Playwright reports are interactive and very helpful
- PROJECT_TRACKER.md is the source of truth for status
