Projects that earned a place on the site.
A curated mix of production systems, personal tools, infrastructure, and experiments worth documenting. This is the tighter public slice, not a complete mirror of every repository.
Featured projects are the strongest current signal. The rest of the archive covers supporting tools, older systems, and site infrastructure.
Use the tags to narrow by domain, or jump to GitHub for the broader stream of repos and experiments.
