Maarten Grootendorst

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 two best-selling O’Reilly books.
