Open Source Mobile Operating Systems Online Food Ordering Systems

An extraordinary food ordering app providing a one-stop-shop solution for clients to order their favorite meals from exceptional chefs near them. Being built as part of course SEG2105 at the University of Ottawa by SEG2105 Group 4. Multiple entities or objects of data representation (User, Client, Chef, Meal, etc.) have to be accessable and modifiable from different parts of the application, and changes in data should be represented on the user interface efficiently. By taking inspiration from the Chain-of-responsibility design pattern, Modal-View-Controller design pattern and the Dispatcher-Action-Handler pattern, we resorted to implementing a code structure and data handling pattern that helps achieve loose coupling, lesser dependency on external frameworks (like Firebase) and more modularization. Every app instance would have UI components (activities), which will only contain code needed for user interface. UI components, use the App instance, to make calls.

Magnificent User Interface that I designed back in 2018 for a project that unfortunately did not come to fruition. However, in the year 2023, I have taken the initiative to transform this aesthetically pleasing design into a fully functional code. This creation has been a labor of love, and I hope that it will capture your attention and admiration. For those who are curious, the original design can be viewed on my Dribbble or Behance account. Please take a moment to immerse yourself in this captivating user interface, and I trust that you will enjoy the experience as much as I have enjoyed bringing it to life.

The application was developed by members of the TTVTT group - students of Ho Chi Minh City University of Technology.
