I build design foundations that companies grow on.
From first principles to scaled systems
I lead product and brand design across live web3 platforms, global events, and on-chain yield ecosystems, taking work from first principles through to systems that scale in the real world.
How I work
Principles first
I work from first principles, treating design as infrastructure rather than surface. My focus is on building systems that reduce complexity, scale across teams and environments, and hold up under real constraints.

Foundational Responsibility
I operate comfortably in ambiguous spaces, often partnering directly with founders and engineers to define structure before form. Brand, product, and operations are treated as a single surface, not separate disciplines.

Quality over novelty
I optimise for longevity over novelty. The goal is not to ship quickly, but to build foundations that make future work easier, clearer, and more consistent.

Experience that proves design isn’t just about visuals, it’s about building brands that can scale from first principles.
Foundations
