Principal Product & Customer Transformation Leader

I turn complexity into customer and commercial progress.

Across banking, insurance, telecommunications, technology and e-commerce, I have built products, redesigned services, secured transformation investment and led teams toward outcomes that can be seen in customer experience, operational performance and the bottom line.

Experience earned in the real world.

I began in commercial kitchens, moved into frontline customer service and then spent eight years inside Telstra learning how complex organisations really work. Entrepreneurship taught me to own every commercial consequence. Insurance and banking brought those experiences together in regulated product leadership.

How I work

I am most useful where the problem crosses organisational boundaries and the easy answer is not the right one.

My work sits at the intersection of customer need, commercial reality, operational design, risk and technology. I look beyond the visible symptom, connect evidence across the system and build a path that people can actually deliver.

Leadership proposition

What I bring to a senior role.

I combine the strategic range to shape a portfolio with enough delivery depth to understand what must happen next. I am comfortable with executives, frontline teams, technology specialists, partners and customers—and with making the connections between them.

Direction

Clear product vision, roadmaps and investment choices grounded in customer evidence, portfolio economics and organisational strategy.

Alignment

The ability to bring product, technology, operations, finance, risk, compliance and partners around a decision and keep momentum when priorities compete.

Outcomes

Accountability for measurable progress—not simply activity—across customer experience, revenue, cost, risk and operational performance.

Let’s talk about what comes next.

I am open to the right conversation: a more senior role with genuine scope, sponsorship and accountability for meaningful customer and commercial outcomes.
