Beyond Work
When not consulting or writing, I spend time with my 7-year old son, who's currently deciding between becoming a professional football player or a machine learning engineer. I also practice Choi Kwang Do, constantly working on improvement — a philosophy I bring to both my martial arts and professional work.
I've lived and worked across six countries, speak several languages, and once volunteered teaching English, Russian, and programming to children in St Petersburg.
