Hi, my name is Hans Hack

This is a selection of my work. I'm a data visualizer, map maker and artist working in Berlin. I work with Javascript (front end and back end), databases, open source GIS tools, image editing programs and whatever might come handy to realise a project. You need help to visualise, get or analyse data, find creative ways to get your message across or just want to have a chat? Feel free to contact me:
