About

I'm a Gameplay Programmer with 4+ years of professional experience building gameplay systems in Unreal Engine 5, C++, and Blueprint Visual Scripting. I specialize in writing modular, efficient code and enjoy exploring new technologies in a constantly changing field.

From an early age, I was an avid admirer of video games, which made me motivated enough to pursue this as a career when I was in college. In June 2020, when COVID-19 delayed my bachelor's studies, I started working remotely as a gameplay programmer 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.

"Mesbah is talented, responsive, great to work with and extremely creative. Recommended 100%."
