Hey there, fellow developer!

Still writing every line of code from scratch? While you're debugging that authentication system, your competitors are shipping twice as fast with AI. Last month, our dev team cut sprint delivery time in half using Claude – and I'm not talking about basic code completion.

Today, I'm sharing the exact prompts that transformed our workflow (with video demonstrations!), from generating production-ready APIs to catching security vulnerabilities before they hit production. Don't let your stack fall behind. Here's couple of examples on how to level up your development game with Claude.ai.

💻 1. Production Code Generation with Claude: When given the below prompt, claude.ai generates the code for us! How cool is that?

Create an API endpoint for user authentication: 
Requirements: 
- JWT implementation 
- Rate limiting 
- Input validation 
- Error handling 
- Swagger documentation

💻 2. Production Code Reviews with Claude Here's a problematic Python code snippet that caused memory leaks and security vulnerabilities in production, let’s check what happens when we ask to analyze this code.

class CacheManager:
    _instance = None
    _cache = {}
    
    @classmethod
    def get_instance(cls):
        if not cls._instance:
            cls._instance = cls()
        return cls._instance
    
    async def fetch_user_data(self, user_id: str) -> dict:
        if user_id in self._cache:
            return self._cache[user_id]
            
        async with aiohttp.ClientSession() as session:
            async with session.get(f'https://api.example.com/users/{user_id}') as response:
                if response.status == 200:
                    data = await response.json()
                    self._cache[user_id] = data
                    return data
                return None

    def bulk_process_transactions(self, transactions: list) -> None:
        processed = []
        for tx in transactions:
            if tx.get('status') == 'pending':
                query = f"UPDATE transactions SET status='processed' WHERE id='{tx['id']}'"
                db.execute(query)
                processed.append(tx)
                
        if processed:
            self.notify_admin(f"Processed {len(processed)} transactions")
            
    def notify_admin(self, message: str) -> None:
        admin_emails = self._cache.get('admin_emails', [])
        for email in admin_emails:
            send_email(email, message)
