One Big Note

A little less interface.
A lot more room to think.

One note, filling the window. The text adjusts as you write, keeping the thought in front of you. A focused Mac app built with AI.

03 / A wider view

Different mediums.
Same curiosity.

The tools change. The attention stays.
A frame, a phrase, a line of code.

My photographic work moves between people and places: portraits, performances, and the quieter details that ask you to look again.

04 / The person behind the work

Curiosity is
the constant.

I’m Mathew. I build software, make images, shape sound, and play trumpet.

I use AI to turn ideas into working apps and websites. I direct the process, make the decisions, and keep refining until the result is useful.

Photography taught me to look closely. Music taught me to listen, practise, and pay attention to timing. Those habits come with me into everything I build.

A little more context

The experience
behind the ideas.

CalArts. The stage. The studio.
And the tools I’m building next.
