About

This is my personal blog site about data science in Python and Rust. I am a computer scientist and insurance mathematician, and currently work at De Nederlandsche Bank. My focus is on knowledge representation, explainable machine learning, natural language processing and data graphs.

All content on this website is written without the use of generative AI models.
