01 About Me

Building worlds, one system at a time

I'm L. Charitha Madhushanka, a Senior Game Developer with an MSc in Computer Games (Distinction) from the University of Essex. For over six years I've shipped commercial games, VR/AR experiences and engine tools — currently as Senior Gameplay Engineer at Ripstone Games on an unannounced PlayStation title.

My focus is the craft behind play: combat and AI, physics-driven mechanics, crowd and pathfinding systems, runtime ECS and Niagara VFX. I also publish high-quality content to the Unreal marketplace — 11 products, 150+ assets used by developers worldwide.
