Senior Frontend Engineer / Tech Lead
Interfaces and interactive experiences, designed and engineered end to end.
About BrianI’m an Irish frontend engineer based in Valencia, working across design systems, web animation and interactive experiences.
My background spans visual art, astrophysics and computer science. For over fifteen years, I’ve been building for the web.
I work mainly in TypeScript and React, and I care about the whole thing — the system underneath and the experience on top.

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. This site is partly a continuation of that fascination — exploring those systems through code.
