CommBank
Finance
CommBank is one of Australia's biggest banks. Millions of people trust it with their money every day, which means every new experience it puts in front of customers has to earn that trust.
New technology moves fast. Banks move carefully. My work sat in between, separating the ideas worth building from the ones that only sounded good.
I was part of an emerging technology team focused on zero-to-one product ideas. I led design across business units, finding where new technology could help customers, validating ideas through research, and shaping the product vision. Then I'd bring them to life through prototyping, design, and delivery.
Most of this work lived in undefined problem spaces, where there was room to experiment and plenty of ideas changed shape along the way.




Cheaper fuel, without the search
Fuel apps put the work on customers, so most people didn't bother. Fuel Finder flipped that around. Using CommBank's transaction data to predict when someone would next need to fill up, it nudged them at the right moment with the cheapest nearby station already found.
I owned design end to end, from customer research and shaping product strategy to prototyping and working with engineers to ship. Rather than build the full product upfront, we ran three experiments: a single push notification to 50,000 customers, a pilot in the CommBank app for 250,000, then a rebuilt experience for all NSW customers.
Over the first ten months, more than 109,000 people opted in, saving an average of 5.45% per fill and almost $2 million in total.




A consolidated view of your credit cards
When your credit cards are spread across different banks, it's easy to lose track of the full picture. Credit Manager brought them together in one place, giving customers a clear view of what they owed, tools to stay on top of repayments, and a path to paying them off faster.
I worked closely with engineers and third-party vendors to understand complex data structures, technical limitations, and tricky edge cases, then translated them into an experience that felt simple and clear for customers.



Spotting scams before they land
Forward a suspicious text message and ScamCheck tells you whether it's likely a scam. When it is, it explains why, pointing out things like unfamiliar senders, suspicious links, or urgency tactics.
In research, people liked the idea of ScamCheck, but felt confident they could spot a scam on their own. The data said otherwise, with 84% of scam complaints over four months coming from text messages. That gap between confidence and reality became the real problem to solve, so I pushed for a deeper round of research to understand why people were falling for scams before we committed to a direction.
Once we decided to build, we partnered with Truyu to get to market quickly, launching ScamCheck inside their iOS and Android apps. I led design across both teams, working with CommBank engineers to map the experience to technical requirements, and with Truyu's product team to design within their existing product.



Connecting customers with local businesses
Local Offers was a pilot within CommBank Yello that let customers find nearby businesses on a map or list, check details like opening hours without leaving the app, and earn cashback straight to their account. It tested whether a more local, personal offers experience would get customers engaging differently.
With two customer groups, existing cashback processes, and Mastercard all in play, this was as much a systems problem as an experience one. It meant bringing the retail and business sides of the bank together, aligning teams that don't usually design for each other's customers. I mapped how everything fit together, then designed for both ends: a simple way for customers to discover and support local businesses, and a worthwhile experience for the business owners taking part.
