Notes on knowledge work, law, and AI tooling.
I work at the intersection of commercial law and major-project delivery. The slow thread running through the writing here is what it takes to do that work well at a moment when the tooling is moving faster than our work environment.

the short version
I'm Commercial & Legal Director at VIDA Roads, with a background spanning private practice, the University of Melbourne, and major-project delivery.
