python-backend

What problem does it solve?

This skill provides an expert Python backend developer to build high-performance APIs, data processing pipelines, and ML-integrated services, saving time on complex backend logic and data handling.

Core Features & Use Cases

• FastAPI Application Development: Implement async route handlers with Pydantic models for validation and OpenAPI documentation.
• Data Processing & ML Integration: Use pandas/numpy for ETL and integrate trained machine learning models for inference.
• Database Operations: Manage SQLAlchemy async sessions, Alembic migrations, and optimized queries for PostgreSQL.
• Use Case: You need a new API to serve predictions from a machine learning model and handle large CSV uploads. Use this skill to create a FastAPI application, integrate with a PostgreSQL database, and implement endpoints for model inference and data processing with pandas.

Quick Start

Use the python-backend skill to create a new FastAPI application with a user registration endpoint, SQLAlchemy for PostgreSQL, and Pydantic validation.
