I am a partner at EY-Parthenon, focused on the intersection of technology, transactions, and transformation. This is the home to my side projects — personal apps built for fun, learning, and the occasional useful thing.

These are my own observations and tinkerings; they don’t necessarily reflect the views of my firm.
