Flask Web Development & Optimization

This skill provides a robust framework for developing scalable and maintainable Python web applications using Flask 3.1.x. It implements the application factory pattern and blueprint modularity to ensure clean codebases while pre-emptively solving nine critical production issues, including stream_with_context regressions, async/gevent conflicts, and session protection bugs. By leveraging modern tooling like uv and established patterns for Flask-SQLAlchemy and Flask-Login, it streamlines the entire development lifecycle from local setup to secure production deployment.
