About

I prioritise research, testing and iteration — then I make the result buildable.

I'm a product designer working between UX research and delivery: understanding real user needs, designing intuitive interfaces aligned with business goals, and improving both satisfaction and conversion with workflows that keep getting optimised against behaviour.

I treat brand identity as part of the experience, not a skin on top of it — and I run projects end-to-end, keeping design and engineering in one conversation from epic to handoff.
