How does it handle data validation?

It implements strict data validation using Pydantic v2, ensuring that all API inputs and outputs are validated and correctly typed before processing.

Can it handle background tasks and queuing?

Yes, it provides patterns for managing long-running tasks using Celery, Redis, and other task queues to keep your main API responsive.

Can it help with database migrations and ORM setup?

Yes, it is proficient in managing database schemas and migrations using tools like Alembic for SQLAlchemy and the native Django ORM migration system.

Does it support machine learning integration?

Absolutely. It includes implementation patterns for loading models from Scikit-learn, TensorFlow, or PyTorch and creating high-performance inference endpoints.

Which Python frameworks does this skill support?

It specializes in FastAPI, Django, and Flask, with a strong emphasis on asynchronous patterns and modern Python best practices.
