Way of work 💡
Research and insights
I begin by clarifying the opportunity, the people it serves and the outcome that matters, building shared direction before the work begins.
AI-assisted discovery
With Claude, I turn research and early conversations into insights, journeys and priorities, keeping human context at the centre.
Build the foundations
I define scalable systems, clear patterns and project structure that make the product easier to build, evolve and maintain.
Team collaboration
I collaborate openly with product and engineering teams, sharing decisions early so momentum stays high from idea to release.
Prototype & test
I build real product experiences with Claude Code, making it faster to iterate, test ideas and learn from working software.
Hi, I'm David! 👋
I’m a product designer and builder with 15+ years of experience turning ambitious ideas into useful digital products.
My workflow is AI-assisted from end to end. I use Claude to think through the product, structure the project and explore options. From there, I use Figma to shape the UX, UI and design system, before using Claude Code to carry those decisions into development. The result is closer collaboration, faster learning and a smoother path from concept to something real.
