I’m Rijnhardt Kotze.

I work with data. I wrangle it, model it and try to get stories out of the numbers.

Away from the screen, I listen to classical music. A devastating cello concerto. A symphony on repeat for a week.

What I write about

  • Data. The tools, the ideas and the rabbit holes I find while working with it.
  • Classical music. Pieces, composers and performances worth your attention. Weinberg’s Cello Concerto is a good place to start.

Sometimes something else. Whatever has my attention at the time.

How to reach me

Write to me about a post, a piece of music or a data problem.
