Xe Iaso is a writer and engineer publishing at xeiaso.net (the "xesite" that serves the blog is her own software, currently v4). She is the author of Anubis, the proof-of-work bot wall that gates a site behind a WebAssembly challenge to price out mass scrapers while letting real browsers through.

Her writing sits where web infrastructure meets low-level detail: WebAssembly internals, reproducible builds, Nix, compiler behavior, and the day-to-day friction of shipping software that has to run in hostile conditions. The posts tend to be first-person build logs — she hits a concrete problem, shows the exact command output, and works through the fix, rather than writing from the outside as a survey.
