👋 Hi there!

Headshot of Jeroen Janssens 📛 I'm Jeroen. Welcome to my site.

💻 I work at Xomnia in Amsterdam as a Senior Machine Learning Engineer.

🐛 Most of my bugs are written in Python, R, JavaScript and Bash. Every now and then I dabble in C and Lua. I should learn Rust.

✍️ I wrote Data Science at the Command Line. The second edition was published by O’Reilly in 2021.

🏫 My online cohort-based course Embrace the Command Line is currently accepting applications for the third cohort, which starts April 3, 2023.

🇳🇱 I live in Rotterdam, the Netherlands with my wife and two kids.

🗽 My wife and I have lived in New York City for 2,5 years. Once I start talking about this, I find it difficult to stop.

🪚 I’m trying to build a Lego table. Still got all my fingers.

📼 I’ve seen Labyrinth (1986) and The Matrix (1999) more times than I care to count.
