Projects

This is a collection of both individual and group software development projects, including web development, console programs, and other GUIs.

Recipe App

An Android app made in Jetpack Compose that features 2-factor authentication for account creation and sign-in.

Users can explore the home screen to view images and videos, manage an ingredients list with editable quantities and expiration dates, and access a camera screen for recording clips with customisable lengths.

I created and tested various UI features, including:

authentication via an email code
recording button that allows multiple videos
gallery that presents the videos and images in a device
a basket that enables multiple items to be added concurrently with attributes

Languages: Kotlin
Framework: Android Jetpack compose
Database: Firebase
IDE: Android Studio 2023

Chat Program:

In my free time, I utilised Django channels by creating a chat program, where an existing user can log in and communicate with another user in the room. Users can create, edit, and delete their messages which are updated for all in real-time.

authentication via login
rich text editor to create detailed messages
messages can be edited or deleted
multiple rooms where users can see texts in real time

Languages: Python, Javascript, HTML, Less
Framework: Django
Database: Django Models

Orbitars

In one of my earlier projects, I developed a Win32 GUI game in C++ called Orbitars. The objective is to avoid and shoot moving asteroids using WASD controls with acceleration and rotation-based movement. The player's ship are rendered with PNG image sprites, and asteroid's via the GUI's graphical drawing.

Rendered PNG sprite graphics
WASD acceleration based movement
Asteroids exponentially increase when broken

Languages: C++
Platform: Win32
IDE:Visual Studio 2019

Real Support Academy web portal

I developed the forum page for the Real Support Academy's web portal using React, focusing on the user interface for viewing and adding messages.

The portal features 2-factor authentication for sign-up and login, providing access to various school courses and a forum.

All account data and forum posts are stored and retrieved from a Firebase database.

authentication via login
multiple courses users can enroll in and use
forum page where messages can be created, edited and deleted

Languages: Javascript extended, Html, Css
Framework: React
Database: Firebase

Preact weather app:

As part of a school group project, I contributed to a Preact weather app for mobile devices that displays London's weather data, including temperature, windspeed, direction, humidity, and weather conditions with icons.

I was responsible for the initial design and layout, as well as implementing the carousel component, enabling users to swipe between different widgets.

Display weather data: temperature, wind speed
Searches based on city location
Varying data depending on the day

Languages: Javascript Extended, HTML, CSS
Frameworks: Preact
Platform: IntelliJ Idea
Dependencies: Weather API
