About me

I’m currently working at Deloitte Australia in their Analytics and AI team, after graduating from a Bachelor of Commerce in Economics and Finance at the University of Melbourne.

After growing up in South Africa, I’ve lived in New Zealand and now Melbourne, Australia. I’ve always enjoyed tinkering in a workshop, and in the absence of power tools this has morphed into tinkering with programming, ML, and electronics. This has spurred on many side projects, some of which are documented above.
