About
I care how things feel and how they work
Design, programming, and new technology have pulled at me since my bachelor’s degree, so I’m studying both sides properly — interaction design at Monash, and now computer science with a focus on AI and HCI at the University of Sydney.
I learn by making: interviewing people, prototyping fast, testing, and refining until an idea holds up. Lately that loop includes AI — as a tool I build with, and as material I tell stories with.
