Hi, I'm Donnovan

Donnovan Feuillastre

Software & Game Developer · France

I build high-performance, modular systems for games. Right now that means Unreal Engine 5 at Spinware, where I work on AI, UI and tooling. Before that came engine work and console shipping at Piece of Cake Studios, then VR at Wanadev Studio and Iconik. I look for environments that combine creative ambition with technical rigour.
