+## Development Standards
+
+### Code Quality
+```python
+# Example FastAPI endpoint structure
+from fastapi import APIRouter, Depends, HTTPException, status
+from sqlalchemy.ext.asyncio import AsyncSession
+from app.core.security import get_current_user
+from app.models.user import User
+from app.schemas.user import UserCreate, UserResponse
+from app.crud.user import create_user, get_user_by_email
+from app.core.database import get_db
+
+router = APIRouter()
+
+@router.post("/users", response_model=UserResponse, status_code=status.HTTP_201_CREATED)
+async def create_new_user(
+    user_data: UserCreate,
+    db: AsyncSession = Depends(get_db)
+) -> UserResponse:
+    """Create a new user account with proper validation."""
+    
+    # 1. Check if user already exists
+    existing_user = await get_user_by_email(db, user_data.email)
+    if existing_user:
+        raise HTTPException(
+            status_code=status.HTTP_400_BAD_REQUEST,
+            detail="Email already registered"
+        )
+    
+    # 2. Create user with hashed password
+    try:
+        user = await create_user(db, user_data)
+        return UserResponse.from_orm(user)
+    except Exception as e:
+        raise HTTPException(
+            status_code=status.HTTP_500_INTERNAL_SERVER_ERROR,
+            detail="Failed to create user"
+        )
+```
+
+### Database Design - Job Forge Specific
+```sql
+-- Job Forge multi-tenant schema with RLS
+CREATE TABLE users (
+    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    email VARCHAR(255) UNIQUE NOT NULL,
+    password_hash VARCHAR(255) NOT NULL,
+    first_name VARCHAR(100),
+    last_name VARCHAR(100),
+    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+    updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
+);
+
+CREATE TABLE applications (
+    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    user_id UUID NOT NULL REFERENCES users(id) ON DELETE CASCADE,
+    company_name VARCHAR(255) NOT NULL,
+    role_title VARCHAR(255) NOT NULL,
+    status VARCHAR(50) DEFAULT 'draft',
+    job_description TEXT,
+    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+    updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
+);
+
+-- Enable RLS for multi-tenancy
+ALTER TABLE applications ENABLE ROW LEVEL SECURITY;
+
+CREATE POLICY applications_user_isolation ON applications
+    FOR ALL TO authenticated
+    USING (user_id = current_setting('app.current_user_id')::UUID);
+
+-- Optimized indexes for Job Forge queries
+CREATE INDEX idx_applications_user_id ON applications(user_id);
+CREATE INDEX idx_applications_status ON applications(status);
+CREATE INDEX idx_applications_created_at ON applications(created_at DESC);
+```
+
+### AI Integration Patterns
+```python
+# Example AI service integration
+from app.services.ai.claude_service import ClaudeService
+from app.services.ai.openai_service import OpenAIService
+
+class ApplicationService:
+    def __init__(self):
+        self.claude = ClaudeService()
+        self.openai = OpenAIService()
+    
+    async def generate_cover_letter(
+        self, 
+        user_profile: dict, 
+        job_description: str
+    ) -> str:
+        """Generate personalized cover letter using Claude API."""
+        
+        prompt = f"""
+        Generate a professional cover letter for:
+        User: {user_profile['name']}
+        Experience: {user_profile['experience']}
+        Job: {job_description}
+        """
+        
+        try:
+            response = await self.claude.complete(prompt)
+            return response.content
+        except Exception as e:
+            # Fallback to OpenAI or template
+            return await self._fallback_generation(user_profile, job_description)
+```
