Principal Product Designer (hands-on, systems-minded)

Senior product designer with 10+ years in startups and 25+ years across design. I work end-to-end across discovery, interaction, systems and delivery, partnering closely with engineers in component-led environments. Strong at reducing product entropy by defining scalable patterns, states and behaviours, and building design systems that survive growth. Comfortable operating with high autonomy, including founder and Head of Design contexts.

Focus areas

Product design craft: interaction, states, behaviour, UX architecture, UI quality
Design systems: components, tokens, theming, pragmatic governance that enables shipping
Engineer-facing design: implementation-aware decisions, documentation, QA loops
Design-to-code delivery: comfortable shipping UI directly in code (when faster than prototypes), reviewing PRs, iterating with engineers
Multi-surface experiences: mobile (iOS/iPadOS/Android), web, hardware-adjacent UX
Communication: workshops, design critiques, decision logs, mentoring
