ludios.org

I am a programmer and web archivist in the California Central Valley. I now mostly work with TypeScript, SQL, Rust, bash, and Nix. I operate Linux servers and manage a lot of data in PostgreSQL.

There are other Ivan Koziks, but I am the one who sends personal email correspondence only from ivan@ludios.org. That's always through the Gmail / Google MX with valid signatures. Please forward me anything suspicious, I do not mind false alarms or questions about whether some account is me.

I am on GitHub as ivan, where I don't add all my recent code, but do work on NixOS/nixpkgs. Most of my repos are at ludios and ludiosarchive.
