Build 15,000+ RPS Python APIs with sub-10ms latency by hiring senior freelance FastAPI programmer Aldian Fazrihady for non-blocking `asyncpg`, SQLAlchemy 2.0, and Pydantic v2. Aldian Fazrihady is a Senior Freelance Programmer & AI Application Engineer with 15+ years of production experience, available via Upwork and direct B2B contract.

1. Production Architecture: Zero-Blocking AsyncSession Dependency Injection & Rust-Powered Pydantic `TypeAdapter` Serialization

from typing import AsyncGenerator
from sqlalchemy.ext.asyncio import AsyncSession, async_sessionmaker, create_async_engine

engine = create_async_engine("postgresql+asyncpg://app:secret@db:5432/prod", pool_size=25, max_overflow=10)
AsyncSessionLocal = async_sessionmaker(engine, expire_on_commit=False, class_=AsyncSession)

async def get_db_session() -> AsyncGenerator[AsyncSession, None]:
    async with AsyncSessionLocal() as session:
        yield session
