If you want to learn how a full stack app works behind the scenes - without frameworks or libraries - this course is for you.

You'll build a Google Calendar clone using PHP, MySQL, JavaScript, HTML, and CSS.

The course covers laying out the UI, wiring up your database, writing the backend logic, and making the app dynamic.
