I’m the Head of AI at the social trading platform wikifolio.com and co-author and maintainer of the project Tidy Finance.

I write about tidy data science with R, Python and Julia on my blog Tidy Intelligence.

I occasionally design shirts and mugs that you can find under the Tidy Swag brand.

I’m also co-organizing events of the Berlin R Users Group.
