What I Do

End-to-End Product Design

I work across discovery, definition, and design, from user research to shipped product, delivering measurable user and business outcomes in complex and regulated product environments.

Design Systems

Enterprise design system architecture, token structuring, Figma-to-code alignment, contribution and governance models, embedded WCAG 2.2 AA compliance.

Design Leadership

I operate as a player-coach, shaping design strategy and aligning stakeholders at senior level, while staying close enough to the work to drive quality execution and delivery.

AI in My Practice

AI is embedded in my daily workflow, designing with AI, and for AI.

AI-Assisted Design Practice

I use AI tools daily to assist my research and design practice. From research synthesis, market analysis, competitor benchmarking, and pattern recocognition, to rapid prototyping with complex interactions and data-heavy logic. Tasks that used to take days, now happen in hours, so we can move quicker and think more deeply.

Stack: Claude Code, Figma MCP, Cursor, Replit, Gemini

Continually revising other tools as they evolve: Figma Make, Google AI Studio, ChatGPT, Codex, Lovable, Perplexity, Co-Pilot

Designing for AI-Powered Products & Services

AI changes what UX has to do. Features that predict, generate and automate need clear mental models, honest error states and interactions that keep humans in control.

I bring experience designing for products where the interface has to make complex, data-driven behaviour feel simple and trustworthy.
