About

I'm a Game Developer with 4+ years of professional experience across gameplay programming, technical design, and 3D art in Unreal Engine 5, C++, and Blueprint Visual Scripting, building modular, data-driven systems that are easy to extend and maintain.

In June 2020, when COVID-19 delayed my bachelor's studies, I started working remotely as a game developer specializing in gameplay systems and mechanics implementation. It grew into four years of professional practice that extended beyond graduation in 2022, before I stepped back to pursue my Master's in Expanded Media at Darmstadt University of Applied Sciences full time. My thesis comparing sensory engagement across VR and non-VR platforms was submitted in March 2026 and is published on Zenodo.
