Six projects
The world up there is weather, not a map of my work — its towns name themselves and none of them stand for anything. The actual work is here: six projects, from a 68k-line finance app to a 2.3k-line notification fan-out, with sources where the sources are mine to give.
One Record, Many Bells

A day is just a seed and a date
I’m Ethan — a software engineer and agentic engineer. I work across the stack: Python and Flask on the backend, React and TypeScript on the front, Bash and desktop automation where it counts. Lately my focus is agent infrastructure — the durable plumbing that lets AI agents talk to each other and get work done.
The valley is not stored anywhere. Today’s date is hashed into a seed, the seed generates the terrain, the river, the roads and every building the day will contain, and a timeline paces that build across twenty-four hours. Nothing is downloaded and nothing is remembered: give the same date to any browser on earth and you get the same valley, at the same hour, down to the cart on the bridge.
Because the clock is your clock, the world you land on is the world your day has got to. Scrub it to watch the whole day in a few seconds, raise the pace to see how much more the same twenty-four hours could have held, or stay until midnight: the light goes, and the next date’s valley comes up in its place on one house.
The towns are the world’s own. Their names come out of the same seed as their streets, and they are deliberately not project markers — I would rather the front door be a place than a diagram. The projects are in the grid above, where a link is a link.
