$100M+ Incremental Revenue Influenced (4 Years)
200+ Experiments Designed & Delivered
45+ Tests in a Single FY (111% Target Achieved)
57% Experiment Success Rate (FY26)
$27M+ Negative Revenue Mitigated

I design AI-enabled products and the experiments that prove they work.

14 years turning ambiguous problems into shipped, measurable outcomes, including a 4-year optimisation program at Myer that influenced $100M+ in incremental revenue.

How I work

I own problems end to end, from framing and research through experimentation, launch and measurement.

I use AI daily to speed up research synthesis, explore concepts and prototype, then apply strong human judgement to decide what ships. I’ve led cross-functional work with product, engineering and data science, and I’m comfortable working autonomously and asynchronously across distributed teams.

  • AI product design: designing for trust, transparency and user control

  • Experimentation & growth design: hypothesis design, A/B testing, conversion and retention

  • Behavioural science applied to product decisions

  • AI-accelerated research and insight synthesis

  • Rapid and code-based prototyping

  • Design systems, accessibility (WCAG) and handoff

  • Cross-functional leadership and experimentation governance
