Edmonton ICU for Android and iOS
This Android and iOS application displays information about various intensive care units (ICUs) around Edmonton, Alberta. The app's front end is relatively simple, displaying text, images, and links depending on the location selected. The more exciting aspect of the application is the back end and companion desktop application used by the ICU staff. The desktop application, written using Windows Presentation Foundation (WPF), allows the hospital staff to update the application's content on the fly, adding or updating images, text, or even entire content sections. Meanwhile, the app regularly checks for updates and seamlessly downloads them without even needing an update from the app store.

Round Robin Form Service

A web app for securely distributing communication among a predefined group of individuals. Details are omitted for the confidentiality of the client.

The client oversaw facilitating communication to a small group of specialists but found that certain specialists were contacted disproportionately, causing an uneven distribution of work. This application was created to evenly distribute these work requests among the group of specialists fairly and anonymously. Administrators create and add a set of embedded forms into the application's database, each form linking to a specific recipient's inbox. When end-users log into the site, they automatically get a form based on previously accessed forms. This ensures a fair distribution of requests in the given group and removes any personal bias from the equation. The site was developed using Django.

Django Wedding Website

This Django website facilitates the communication of RSVPs and event information for weddings. The client wanted to use Django over a CMS system like WordPress to allow more freedom to customize every site element to their specifications. I used a CSS library from Pixelarity to reduce the work on the front end and built the rest of the site using Django. I wrote a few functions, allowing the client to download a CSV export of the guests' current status and quickly get an overview of where things were. I used a Vultr Ubuntu virtual machine to deploy the site, using Nginx and Gunicorn. Overall, the website was pretty straightforward, and the client was satisfied with what they received.
A website for gathering customer data for analysis and market planning. While the site appears relatively simple to a public user, administrators have access to a wide variety of functions, including monitoring user activity on the site, responding to the site form, and editing much of this content on the fly without any technical knowledge.

Facility Sign-in App

A lightweight Android/iOS application for signing in and out of the building in which the client operates.

Given their large facility, the client had issues with staff leaving and setting the alarm while others were still in the building. They wanted an app available on user devices and on mounted tablets by the entrances to allow users to sign in and out of the building and ensure that no one else was present.

I designed the iOS and Android app and the accompanying back end that handles the sign-in and sign-out. The back end was built using the Django REST framework.

Solo Game Development
The project URL here contains a link to my profile, which lists all the games I have released. I have primarily worked with Unity and Pygame and have been rapidly improving my game development skills over the past two years. I performed scripting, graphical asset management, performance optimization, and multi-platform deployment processes through my experience building games. I continue developing games at any given opportunity and am excited to build something that shines soon.
