Experience
High on Life VR
https://www.youtube.com/watch?v=EQziBgQgrJIPorting "High on Life", a PC and console video game, to VR platforms, including Meta Quest 3.
"High on Life" is a comedic first-person shooter where an alien cartel invades Earth to use humans as a drug. Players team up with foul-mouthed, sentient alien guns to become intergalactic bounty hunters, explore diverse alien worlds, and save humanity.
My work involves gameplay development, CPU and GPU optimizations, and VR interaction plugin creation in both C++ and Blueprints within Unreal Engine.

Quest Challenge Application
https://www.youtube.com/watch?v=ABiT5iSN8EYAn application developed with Unreal Engine 4 and I completed the app in one month in my free time. The application is a quest that, when completed, revealed my personal request for the "players" to be the godparents of my then-unborn twin children.
This 6-step challenge starts with a jigsaw puzzle representing the Sheikah alphabet from The Legend of Zelda: Breath of the Wild. A QR code on the back of the puzzle leads to the 2nd trial—a web page containing a quiz where questions are written with the Sheikah alphabet. When all the correct answers are given, an instruction page is displayed to the user so they can download and play the app until the final and surprising trial: the godparent request.
