Public work.
Public proof.

Trying to give the Internet back some of what we take from it. Software I built and published, talks, and articles on AI and engineering — all in the open, all verifiable. Claims are cheap; shipped work isn't.

czSQLServerGit

Every CREATE, ALTER and DROP becomes a Git commit authored by the login that made it — detected inside SQL Server by a DDL trigger and queued through Service Broker, so developers never wait and nothing depends on their discipline. A small utility database, standard SQL Server features and Git: nothing you won't understand. Open source under MIT.
