I’m an independent expert in finance & data and provide services and trainings related to data infrastructure, data analysis, machine learning, and general data science topics.

Previously, I was the Head of AI, Director of Product, and Head of BI & Data Science at the social trading platform wikifolio.com

I’m also co-creator 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.
