I wanted to create an e-learning website where people could purchase online courses. It needed the following features:

• Course list page
• Search page
• Details page for each course
• Cart page
• Sign in / sign up pages
• Checkout page

I also wanted courses to have videos, assignments, and other files, so I knew I needed some way to store them.

I decided to create the website with JavaScript, React, TypeScript, and Material UI. Instead of using an existing e-commerce framework, I decided to create a custom back-end with Node, Express, and Mongoose. I used Amazon Web Services (AWS) for storing video files securely and used Stripe for processing payments.
