My name is David, I am a finance and technology writer from the United States. I’m a former bank manager and corporate finance and accounting professional, left my day job in 2016 to take my online side hustle full time. My primary interest is financial market structure. I write about market platforms, index instruments, and exchange management firms primarily. I was a member of the team that introduced index trading at the CME. Later, I pioneered the secondary market trading of OTC interest rate swaps. In my spare time, I enjoy reading self-growth books.
