Product Design Intern

Oct 2015Dec 2015

Part of a small team tasked with designing an anti-fraud focused pilot project. Designed a platform allowing for node-based graphing, time-based visualization for object frequency analysis, and a rich data exploration interface.

Earlier in my career, I was Head of Product and Design at Spaceship (later acquired by eToro); contracted for many clients through R/GA and a handful of other roles you can read about on my LinkedIn. I've also been fortunate to work with many great companies such as Australian Ethical, Canva, Clipchamp, Google, National Geographic, Nike, R/GA, Timberland, Toyota, Westfield and many more. I rebranded ESLint and redesigned the Node.js website.
