Hi there 👋

I'm a big fan of FOSS and develop and maintain a few tools as side-projects. I also sometimes write technical and educational articles on my blog.

Here's some of my open-source work (most recent first):

isbn-visualization: Visualizing all books of the world in ISBN-Space

An interactive visualization that maps the entire ISBN-space of over 100 million books using a custom "bookshelf" space-filling curve, allowing users to explore publication dates, publishers, and availability across the two billion possible ISBN slots.

This project won first prize in a book metadata visualization contest with a $10,000 prize pool.
