I'm a Senior Technologist and photographer based in Bristol, UK. I explore the world through code, sound, and image.

My work connects the physical and digital worlds - taking inputs from the analogue environment, transforming them through code, and producing meaningful, reliable outputs. From investigating AI safety to documentary photography, I am always exploring new ways to understand and analyze the world.

This site showcases my photography alongside the software I build. For a broader perspective on my work in technology, sound, and systems architecture, please visit the about me page.
