• Course Enrollment: Users can purchase/enroll in courses.
• Secure & Validated: Uses bcrypt for password hashing and zod for robust input validation.
• Simple Frontend: A clean, responsive frontend built with vanilla HTML, CSS, and JavaScript.

🛠️ Tech Stack

• Backend: Node.js, Express.js
• Database: MongoDB with Mongoose
• Authentication: JSON Web Tokens (JWT)
• Validation: Zod
• Security: bcrypt
• Development: Nodemon
