About

I wear many hats. I write to figure out which one fits.

Software engineer by trade, generalist by disposition. I work across the full stack, think about product and design, and occasionally wander into mathematics and music. This site is where those threads come together.

Work

I build software — backends, frontends, the infrastructure in between, and sometimes the product strategy that decides what gets built at all. I care about the parts most engineers don't bill time for: what the error message sounds like, whether the abstraction leaks in the wrong place, and if the thing we shipped is actually the thing people needed.

I've learned that the best engineers aren't the ones who know the most tools. They're the ones who can see the system clearly enough to know which tool to reach for, and when to build something new instead.

Writing

I write long form because short takes are for opinions. Long form is for figuring out what you actually think. If I can't write it out completely, I probably don't understand it yet.

The topics here don't have a through-line beyond my own attention span: software architecture, design tradeoffs, mathematics, music theory, complexity. What they share is that I thought about them long enough to have something to say.

Right now

Obsessed withThe connection between mathematics and music. Fourier transforms, Lissajous figures, the wave equation — the same structures appear everywhere.
ReadingGödel, Escher, Bach by Douglas Hofstadter. Still the best book ever written about the nature of self-reference and emergent meaning.
BuildingInteractive long-form content — posts with runnable Python simulations, playable MIDI compositions, and live-rendered mathematics. The medium should match the subject.
Thinking aboutWhat it means for software to be well-written in the same sense that prose is. Structure, clarity, the right level of abstraction.
