Daniel Kirsch

I am excited about data products - from the ML through the data infrastructure up to the UX. I've worn many hats like data engineer, data scientist, data product manager, product analyst (even full-stack web developer). I have built and led teams building data products. I speak many programming languages - preferrably functional ones. Founder of a data for good non-profit. Creator of detexify. Math diploma from University of Münster.
