Akwya is an Online Learning System that works with professional instructors to offer online courses, through which individuals can attend pre-recorded courses online. These courses provide quizzes for the user to test his/her understanding of the course; and upon completion, certifications shall be acquired.

• This Website was created as a group project for the CSEN704 Course (Advanced Computer Lab).
• After the COVID-19 pandemic that started in late 2019, learning methods have been shifted worldwide to online methodologies. Since then, online courses have been more convenient to most students so the demand for websites like Akwya has been on the rise.
• Shaping the ultimate online learning experience was a very fruitful challenge for us.
• The purpose of creating such project was to practice
  • The MERN (MongoDB , ExpressJS , ReactJS, NodeJS) Technology Stack.
  • Agile software development
  • Up-to-date backend and frontend development techniques

The current build of the project contains no bugs, errors or malfunctions, except for the following:

• Logging in after resetting password requires hashing the password
• Some UI elements need to look more consistent

Future releases will contain additional features and unit tests.

• We used MVC (Model View Controller). For more info visit https://en.wikipedia.org/wiki/Model–view–controller
• Standard coding style is used to ensure our project's readability and maintainability to developers at any level.
• Local variables were declared using the standard naming convention, camel case.
• Prettier extension in Visual Studio Code was used in important files to organize spacing and readability.

This system is used by the following:

• Admins: Administrators who run the website and are in control of everything.
• Instructors: Highly qualified instructors bring a wealth of knowledge and experience to our courses and provide students with exceptional material.
• Individual Trainees: Regular registered user.
• Corporate Trainees: User who is part of partnered company.
• Guests: Unregistered user who can only preview features without using them.
