Software engineer. Interested in systems, technology, economics, philosophy and how things work.

I write at Articulation, build the occasional independent project, and keep a little background here.

Writing

Essays, notes and experiments, on their own site.

Articulation

Making the implicit explicit.

Essays, evolving notes, interactive explanations and experiments across software, philosophy, economics, institutions, history and whatever else seems worth thinking through carefully.

Projects

Independent things I’ve built. Each lives at its own address.

  • Mono

    A companion for focus and the structure of a working day.

    Mono learns the shape of your day, fills the free time with focus blocks and asks you to name one thing each block is for. It is local-first: everything stays in the browser, with no account, server or sync. A small Chromium extension can block distracting sites during a session.

  • Digest

    A distraction-free viewer for YouTube playlists.

    Paste a playlist or video URL and watch it in a stripped-down player surrounded only by your own queue: no sidebar recommendations, no autoplay into unrelated videos, no end-screen grid. Lists and watch progress stay in the browser; a small serverless layer handles Google sign-in and keeps credentials out of page scripts.

About

I’m a software engineer, working mostly on backend systems in .NET and C#. Within software, I’m most interested in architecture and distributed systems: how systems are divided, how their parts communicate, and what happens when that communication fails.

Outside of software I read and think about economics, philosophy, political economy, institutions and history — less as separate subjects than as different ways of asking how complex systems come to work the way they do. I write about these things at Articulation, and occasionally build small tools when a problem seems worth solving properly.
