What I do
Most of what I make ends up on this site. The writing is here, the games are here with an archive of every past day, and Projects describes the four things I work on in enough detail to check: six daily puzzle generators, a customer CMS and publishing pipeline, a content ingestion API, and the site itself.
If there is a thread running through them, it is a preference for deciding things by measurement. The puzzle generators pick their board sizes from exhaustive counts rather than from what looked about right, and they prove a day's board has one answer before serving it instead of trusting the construction that made it.
