This site is no longer simply an extension of my CV. It’s an evolving body of work. A place where tools are built, ideas are stress-tested, and curiosity is treated as a serious discipline. If you’re here to learn, question, calculate, or sanity-check something important (or something oddly specific), you’re probably in the right place. If you have any questions, or would like to discuss further, please contact me here.
