Learn to build and deploy a complete full-stack web application using Python Flask and PostgreSQL in this hands-on 24-minute tutorial. Transform a static "Hello World" webpage into a dynamic social media-style application with a live database, then publish it to the web for free. Start by cloning starter files and setting up your Flask project structure, then create a live PostgreSQL database on Sevalla hosting platform. Master essential database concepts including SQL table creation, CSV data import, primary keys, and data types like VARCHAR and NOT NULL constraints. Connect Python to PostgreSQL using the psycopg library and convert static HTML templates into dynamic, database-driven pages that pull user profiles from your SQL database. Implement dynamic user routes with URL parameters, create navigation bars with database loops, and properly handle environment variables to protect sensitive information like database credentials. Deploy your complete application using GitHub integration, troubleshoot real deployment errors by reading logs, and see your finished social media app running live on the internet. Gain practical experience with full-stack development concepts including Flask web framework fundamentals, PostgreSQL database management, Python-to-database connections, dynamic web page generation, secure deployment practices, and production-ready application architecture.
