My name is David. I have a lot of interests, but mostly I just like to figure out how the world works.

I began my professional life as a US Sailing–certified instructor at Longshore Sailing School. Once I finished school, I went to work at a small federal contractor in the world of cybersecurity. After a brief stint as a quant at a hedgefund, I worked at startup called ThreatKey to help companies manage the overwhelming prospect of keeping their cloud and SaaS environments configured securely. During that time, I also helped show tourists around the San Francisco Bay on a 2003 America’s Cup boat (USA 76). I then went to Apple, where I did some contract work organizing data for their financial analysts and forecasters.

In case it’s not obvious, this is a personal blog. Everything I write here is my own opinion.
