Interaction Design & Prototyping

I prototype ideas and design interactions for Google in Sydney, Australia.

Officially, I’m a user experience engineer. At Google, that means I prototype hundreds of ideas, evaluate them, and toss the bad ones. My teammates and I take what’s left and build them into real products that make people powerful.

But most of what I do is about communication.

I joined the industry around the time the first iPhone was introduced. Much has changed since then, and our devices have become exponentially more capable. A lot of people, especially those living in countries like Mexico or India, use mobile devices exclusively. Some run small businesses off tablets, others keep digital currencies on their phones. As we continue to expect more from technology, our design tools need to keep up to deliver intuitive and powerful experiences. It’s no longer good enough to make something visually appealing; our products need to *feel* right too.

But "feel" is both intangible and ambiguous. The factors that make our products delightful – eg. user needs and visual polish – often get lost in translation from concept to design to implementation. This is where I come in with my prototypes. I bridge gaps in communication between visual design, product management, and software engineering to make sure execution isn’t compromised. Ideas are cheap, execution is everything.

Prior to joining Google, I developed web-based products for Inkling and designed Venmo’s mobile payment apps. I've done product-level thinking, information architecture, visual design, and front-end engineering. It takes a loose mixture of them all to do what I do best: take an idea from seedling to prototype to execution.
