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.

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.

Yumniastic is an online food delivery service app built with Flutter and Django.

HotPlate Online is a simple program that allows customers to order food online and have it delivered. At the moment, this program only works for Windows operating systems, but there are plans to expand to Android, IOS and MacOS. Software and illustrations was created by Andrew Collin. When you first open this program, you'll be greeted with the Main Store Page. On this page you can add your favorite food into the cart. There are multiple categories you can choose from for faster and more organized user experience. Once you add an item, the button will change color and the text will change to "add more". This means that you have 1 or more of this item in the cart. You can check your shopping cart or remove items by clicking on the shopping cart icon on the lower left. This will transfer you to the Checkout Page. On the main page, you also have access to your account information.

This App is designed for Next Door Lounge. It helps the staff to keep track of the reservations and tables of the restaurant. I design it to be easy to use and intuitive. It uses a Firebase as a back-end server and React Native as a front-end. It communicates all changes in real time across all the apps. The solution that I set out to find with this app is about communicating more efficiently with everyone and shorten the amount of time it takes to look at a table that belongs to a reservation. Every night, changes happen: reservations get canceled, tables get switched, and people get added. Everyone should know about these changes, but it takes time to track everyone down, tell them, and make a drawing on their table sheets. That's why thought: What if we could have the table sheet, live on our phone? This way If anyone needs to make a change, we can all see it in real time.

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