Back in 2008 I worked on Blender-Aid - a tool to analyze and refactor production blend files. In 2010 I started work on the new Blender Tiles Compositor. In 2016 I started B3D101 to teach young students about Blender. Currently I'm working on a Crowd Simulation add-on for Blender. I also give training to absolute beginners at the Blender Institute. An now and then I patch some bugs in blender.
