Financial Services, FinTech, and Complex Situations
I'm curious by nature, and I spend most of my time on financial services and fintech. I trained in mathematics and financial economics and began my career as a property and casualty actuary. I keep this site as a place to write down what I learn about investing, mathematics, and economics, along with what I care about outside work.
