👋 I'm Maarten!

As a psychologist turned AI engineer, I'm interested in making AI accessible through highly visual guides.

By taking a rather unorthodox path towards AI engineering, I have been fortunate to have explored and experienced interesting opportunities. From open-sourcing popular packages and collaborating with big-tech, to creating a newsletter and writing an O'Reilly book.

Fun facts

Mamba and SSMs

A Visual Guide to
Quantization

A Visual Guide to
Reasoning LLMs

And of course, the 9 distance measures in data science post:
