This Flask Course takes you beyond basic tutorials into production-grade backend development. You’ll work with Flask 3.x, Jinja2 templating, Flask-SQLAlchemy, JWT-based authentication, and RESTful API design, then containerize and deploy applications with Dockeron AWS or Heroku. Live instructor-led sessions combine with hands-on labs, so you leave with a working portfolio, practical debugging skills, and the confidence to build, secure, and ship Flask applications on a real development team.
