I've developed stock market backtesters, automated options trading software (which actually perform live trading), particle effect editors, a media library for C, mission scripters for my custom game engines, tools for my PhD research, and many more.
My languages of choice are C and C++. I'm also highly experienced in C# .NET, Swift, Java, and Python.
Fornax is a general-purpose particle editor I use in many of my projects. The interface was made in C# .NET, and the preview functionality was built in C++ with OpenGL.
Source code is available here.
The scripting and mission layout tool I built to script missions in Hypergate. It was made in C# .NET.
Some output from a suite of back-testing tools I wrote to develop and test options trading strategies on the S&P 500. These tools were built using C++ and Python.
My automated trading software, written in C# .NET, running on a wall-mounted tablet.
Screenshot of the drone simulation and control software I wrote that powered my drone experiments for my PhD research.

My games and game engines are cross-platform (Windows and Linux) and written from scratch, because I enjoy the learning that comes from doing things yourself. I've also built scripting tools, physically-based rendering (PBR) and raytracing engines, and more.
My games were written in C++ with modern OpenGL and GLSL. Most of my custom development tools were written in C# .NET. I constructed art assets in Blender and GIMP (most recently using a PBR metallicity workflow), and I performed sound design using Goldwave and Audacity. Two of my games are on Steam.
Hypergate is a 3D space combat game available on Steam for Windows and Linux. It took five years to develop.
Check out the Steam Store page here.
Asteroids Millennium is a modern take on an old classic, available on Steam for Windows and Linux.
Check out the Steam Store page here.
Secrets of Mars is a game about an autonomous rover that begins to question reality, and its own programming, when things on Mars begin to become strange.
Development is currently on hold.
A game that I developed in 48 hours for my submission to the 45th Ludum Dare "Compo" competition using my open-source C media library, SIGIL. It ranked 360th out of 2613 submissions!
Source code is available here.
No-Fly-Zone is a short survival-based first-person shooter (FPS) where you must defend yourself against rogue drones. It was made as a simple open-source example of how to create an FPS using OpenGL.
Source code is available here.
This is a render from a raytracing engine I wrote. It features bounding volumes and other techniques for faster rendering, although not in real-time. The object in the center is a mirror.
Projects of mine include an electric scooter, remote controlled vehicles, robots, drones, and more. I modelled them using Fusion 360, and used DipTrace to design the PCBs. The renders below were made in Blender. Most of my devices are powered by Microchip (formerly Atmel) MCUs such as the ATmega328.
An animated render of the µBee, an inexpensive, 3D-printed drone I designed from scratch. Optional mounts for reflective markers allow integration with a motion capture system. I used these drones to conduct my PhD research.
An animated render of an electric scooter. I built it from scratch using plywood, aluminum, and 3D-printed parts reinforced with steel. An ATMega328P powers the logic, motor control, and display.
An animated render of my rugged-terrain, differential drive remote-controlled car. It is nearly entirely 3D-printed, including the controller.
A brief test of a small µBee fleet, detected and controlled by custom software I wrote that also doubles as a simulator to test out behaviours beforehand. A Vicon motion capture system surrounding the lab space captures the 9.5mm markers attached to the drones. For size and weight considerations, only 3 reflective markers are used per drone. The software controlling the µBees detects and tracks these markers over time to associate the detections with drone IDs.
Myself, test-flying the µBee. With the optional motion capture markers, the drone weighs 37g (including the LiPo battery), and has a flight time of up to 3 and a half minutes.
Myself, riding the electric scooter. Its top speed is approximately 16km/h and it has a modest maximum range of about 7km when powered with a 3.3Ah 6s LiPo.
Field tests of the rugged-terrain remote-controlled car on the SFU campus.
An earlier robotics project of mine started prior to my master's degree. A custom global vision system captures the 3pi robots and instructs them to maintain various formations as robots are added or removed in real time.
A digital clock I built using 3D-printed parts, a real-time clock module, 3 LED matrices, and a custom-designed PCB. The power cable runs into and down behind the wall.
While working on my master's degree at the University of Manitoba, I was a sessional instructor from 2013 to 2015. In total, I taught 7 classes, ranging in size from 30 to over 100 students. While course topics were determined by the department, I developed and presented my own lecture content and assignments. Exams were developed and graded jointly between myself and the other instructors teaching the remaining sections. I received excellent ratings from students during evaluations.
I've been active in the Computer Science and robotics communities since my undergraduate career. My volunteer work includes organizing student events for international conferences, and contributing to committees on both local and international levels.
I'm on LinkedIn, and I also maintain websites for Hypergate and SIGIL, and have a GitLab repository with some small public projects.
