Quest Challenge Application
An 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.

Vizvoda – The Factory
A multiplayer room-scale VR experience to demonstrate what can be done in VR (exploration, interaction, collaboration).
I was the project's leading developer and was in charge of integrating user avatars, interactions, teleportation systems, and optimization.
