Is anyone actually reading these blog posts? Do they really need to say anything? I can keep going all day. At least AI can... Claude, keep going, please.

If you're still using SQLAlchemy 1.x patterns, it's time to upgrade. The new 2.0 style with select() and mapped_column() is much more explicit and works beautifully with async.

Use path parameters for required resource identifiers (/users/123) and query parameters for optional filters (/posts?author=corey&limit=10). FastAPI handles both beautifully with automatic validation.

Getting CORS errors? FastAPI's CORSMiddleware is your friend. Just remember: be specific about allowed origins in production. Don't use '*' unless you really mean it.

Protect your API from abuse with rate limiting. Too many requests? Return 429 Too Many Requests. Your server (and your wallet) will thank you.

Async bugs can be tricky. Use logging liberally, understand the event loop, and don't mix sync and async without care. asyncio.run() is your entry point.

Add security headers to your responses: X-Content-Type-Options, X-Frame-Options, Content-Security-Policy. Small effort, big security improvement.
