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.
