What I bring

Design craft meets analytical rigour

UX Research

Great design starts with understanding people. I translate data into action, helping teams prioritise features, refine flows and measure success through usability testing, interviews and experimentation.

Product Design

From discovery to high-fidelity delivery, I translate research and analytics into scalable product experiences that improve usability, adoption and measurable business impact.
