Senior Frontend Engineer / Tech Lead
I’m an Irish senior frontend engineer living in Valencia, building for the web with an eye for design and motion.
About BrianWith a background in visual art, astrophysics and computer science, I bring both visual and analytical thinking to my work.
I started my programming journey as a kid with a book on C. These days I develop mostly in TypeScript, React and Next.js.
Outside of work, I’m fascinated by physics & philosophy and enjoy playing guitar, photography and poker.

About this site
My interest in mathematical art started with my father’s copies of Scientific American. I was fascinated by the illustrations - images where mathematics became something visual, intricate and unexpectedly beautiful.
Penrose tilings stayed with me in particular: a small set of simple shapes capable of producing structure that never quite repeats. The imagery in this site is based around Penrose tiling.
