Work

Marquis

In production since May 2026

An AI-native media intelligence platform run entirely through conversation. Built by one engineer for a PR firm. It watches coverage around the clock, decides what is about the client, and delivers briefs to Slack.

Writing

How I code with AI

How my workflow changed once agents write the code: I plan and write specs, a fleet of Claude instances does the typing, and reviewing and merging stay with me.

Thank You, America

A note of thanks on America's 250th, for every opportunity and for everyone who paid for this freedom.

Why I default to soft deletes: customers get an undo button, and an AI agent that goes rogue in your system can only ever do reversible damage.

Building Marquis

My wife's PR firm tracked media coverage in a spreadsheet. I asked if they wanted something better. Two months later, Marquis went live.

I built a media intelligence platform for a small PR firm over two months. About three-quarters of it got written on my phone.
