About —

I currently run Insitu Digital, a lean design studio creating brands and websites that help businesses launch, grow, and refresh. I also take on select freelance projects, like OnEarly, an AI health startup I helped take from 0 to 1. In past roles, I’ve mentored designers at different stages of their careers, sharing approaches to design systems, product thinking, and customer-led frameworks.

Before this, I was Principal Product Designer at CarExpert, a scale-up reshaping the car-buying experience. I led the redesign of the end-to-end consumer journey and built a design system to support growth ahead of the company’s 2025 IPO, working closely with the Founder, CEO, and Head of Product. I also ran workshops and coached stakeholders to embed customer-centred practices into the product roadmap.

Earlier, I spent 6 years at Jumbo Interactive, starting as a Product Designer on Oz Lotteries, Australia’s largest online lottery reseller with over 3 million customers, and progressing to Principal Product Designer, where I managed and mentored a team of designers across every business vertical. I was a strong advocate for user testing and the Jobs To Be Done (JTBD) framework, ensuring our work aligned tightly with customer needs. This approach consistently delivered product solutions that were undeniable, centred on the customer experience and driving measurable results.

Before Jumbo, I was Lead UX Designer at Vivo Group, designing websites for Poolwerx and Spicers Retreat. While valuable, I wanted more direct interaction with end users. The ability to iterate based on real feedback and inject more passion into the work. Which wasn’t always possible in an agency setting.

I started my career at BCM, one of Brisbane’s largest advertising agencies, where I built a strong work ethic, a broad set of design skills, and an eye for detail. I began with social posts, eDMs, and web banners (we all start somewhere), and soon moved on to high-profile campaigns, websites, apps, and VR experiences for clients like QUT, TMR, Capilano, and Bundaberg Brewed Drinks. I also supported the motion design team, diving into After Effects and Cinema 4D (which is still a love of mine to this day).
