Hi, I'm Rainer. I create software for people working with data.
I specialize in the design of tools that help people explore, analyze and manage data more easily. I am passionate about maps, and in many of my projects, I have dealt with spatial or cartographic data.
I am also the maintainer of the Annotorious and RecogitoJS open source libraries for text and image annotation, and the former lead developer of the award-winning and song-inspiring Recogito annotation platform.
