A bit about me

I love solving problems.

Especially nice meaty 🍖 problems that haven't been solved before.

I’m currently Staff Product Designer in the AI x Growth team at Sanity helping developers and content teams alike leverage content as context to power applications and AI agents.

I love defining strategy and have a skill for sharpening briefs and uncovering insights. I believe in creating user-centred designs where form and function go hand-in-hand. I apply these design principles to any product, whether tangible or digital and always aim to create the most beautiful solutions.

I have worked with big brands and small start-ups, dealt with clients and led design teams. I’m passionate about the craft and process, from designing digital products to sunglasses 🕶️ furniture 🪑 surfboards 🏄 I’ll have at a go at anything!
