Description

I’m a senior product designer with experience taking 3 major platform from idea to scale. I compress the gap between strategy and execution, moving smarter with AI tools, design craft, and commercial judgment.

I have worked as a founder and product leader, raising £3.4m across multiple ventures, taking 3 products from 0->1, closing enterprise deals, and building multidisciplinary teams while remaining hands on with design.

My last 0->1 product onboarded 500k users, 25k subscribers and 30k MAUs in < 12 months. I was the Product Director for France's 2018 Fintech of the Year. These products secured customers including BNP Paribas, AXA, Goethe Institut, Veritree, ONE Championship, Claynosaurz, Humanity Protocol and Plume Network.

I'm particularly effective in data heavy, technically complex environments that require design and product to work closely with engineering to understand very specific user workflows.
