Interests

When I'm not dabbling in code, I enjoy spending most of my time outdoors. I enjoy hiking/trekking, camping, boating, water skiing and tennis.

I love to travel, exploring new places and cultures. Recently I've started getting into Drone photography, playing around with a DJI Spark on my trips.

You'll also find me catching up with friends, maybe even at the pub over a craft beer. :)

Get in touch

You can contact me through the form below or at hello@dcg.nz. I'm normally quite good and should get back to you within roughly a day, but if I'm 'off the grid' then it could be a bit longer (say a week).
