About
Thirty years of building.
Still asking why it doesn't work better.
I wrote my first code at eight, typing BASIC line by line from a magazine into an Atari 800. I built my first website at 22, a Rush fan site that probably broke every design rule that existed. Thirty years later, I'm still doing the same thing: staring at something on a screen and asking why it doesn't work better.
I design from the gaps I actually live in. Spotify is my most-used app, and the Recently Played shelf had blind spots that bothered me for years. I dealt with plantar fasciitis, toenail fungus, and the quiet shame men carry about neglecting their own bodies, so I built a resource for it. Each project starts with a real problem I can feel, not a brief I was handed.
At 56, I still learn like I'm running out of time. I'm teaching myself Hiragana. I walk five miles a day, building back toward a marathon. I meditate. I watch birds. I read everything. If that sounds like someone with too many interests, you're probably right. But the curiosity is the same muscle I use in research. I just don't turn it off.

How I work
Figma comes last. By the time I open it, the research, the brief, and the structure have already done most of the work. The interface is the last step, not the first place I look for answers.
