Portfolio Showreel
This showreel displays some of the many games and apps I've built in the past decade.

My past projects include mobile games covering a large variety of genres, a simulation aimed to train NSW firefighters, and AR/VR experiences.

Some of the games genres I've worked on include but are not limited to are endless runner, clicker, match-3, physics-based, puzzle, racing, TGC, RPG, and hyper-casual.

In all the projects displayed in the showreeI, I built from the ground up or wrote most of the application.
