I’ve lived in Israel, Argentina, and Boston, and currently live in the San Francisco Bay area.

I graduated from Boston University with a degree in political philosophy.

I love motorcycling, sailing, skiing, and traveling.

I like woodworking, DIY projects, and (of course) technology.

My wife and I have a travel blog about our year in Argentina and many other adventures.
