Open Source software developer, photographer, drummer, and electronics tinkerer


Hi, I’m Sybren Stüvel. I work as Blender developer, where I oversee the Animation & Rigging module, and work on pipeline tooling, the dependency graph, and the integration of various file formats. Apart from my work on Blender, I also develop various other Open Source projects, such as Python-RSA and Skyfill.

On this website you’ll also find other nerdy things, like my own DIY electronics projects, my photography stuff, and my archive of UnrealTower, my old Unreal Tournament modding site.
