$ cat ./about.md

Operator notes.

I build things that take the terminal seriously — apps, games, and one multi-agent trading system. The throughline isn't terminal as aesthetic; it's the operator's mental model: small composable verbs, deterministic loops, and a persistent log of what happened.

Stack-wise: Swift / SwiftUI / SwiftData on Apple platforms, React + Vite on the web, Python + Docker for systems work. Generated Xcode projects, CI gates, and a bias toward making things diffable and testable from day one.
