What is Dunder Data?

Dunder Data is a professional training company founded by Ted Petrou (me) dedicated to teaching python, data science, and machine learning. I strive to deliver the very best possible courses with the most precise and effective material.

"Once I took the boot camp, my thinking as a data scientist really developed because Ted really focuses on becoming independent - to think like a data scientist, to ask the main question that guides the entire project."

Sayantan Mitra

"The way that he is open to questions, how he engaged with the actual students during the boot camp, he fostered communication between every one of us."
