I'm a software engineer building infrastructure for AI research. My focus is the layer under the experiments: environments that rebuild the same way every time, dependencies that are pinned and scanned, and CI that fails for the right reasons, so a result can be trusted and repeated.

Most of my public work is one connected system. standards holds the engineering rules and the reusable workflows that enforce them, called by link so a fix lands once and reaches every repository. path is the template new repositories start from, and markdown draws READMEs like this one from data measured on a schedule.

• Working on: reproducible environments, supply-chain hygiene (pinned dependencies, secret scanning, CodeQL and SBOMs), and CI that fails for the right reasons.
• Building with: Python (standard library first), GitHub Actions, Bash and Make, plus dev containers and Codespaces so a Mac and a fresh container start from the same shell.
• How I work: standards a machine enforces, small reviewable changes, Conventional Commits, and signed commits on protected branches.
• Ask me about: reusable workflows, dependency pinning, release automation, and automating the chores nobody should do by hand.

Four games, Chess, Checkers, Pentago and Tic-Tac, with me on one side and everyone else on GitHub on the other. I always play White, and X in Tic-Tac.

1. Pick a move from the list under a board. Chess is always in view, and the other three open with a click.
2. Tick the box in the issue its link opens, then submit it, its title unchanged. The box agrees to the rules and to the games showing your move, username and avatar. The first move to reach the game is the one played.
3. The Official Arbiter rules on it within a few minutes: it answers on your issue, closes it as played or turned away, and redraws the board.

Each side has a week to move, or the Arbiter moves for it at random. A win counts for the player who makes the winning move, and the most wins top the Hall of Fame below.

📖 The rules and everything else are in Games and each game's guide: Chess, Checkers, Pentago and Tic-Tac.

Anyone but @tannergolden can play on this turn, and the first pick in is played. The move is due by 7 Nov, 12:43 EST, or the Arbiter plays a random legal move.

Only @tannergolden can play on this turn: a pick from anyone else is turned away with a comment on its issue. The move is due by 3 Nov, 20:21 EST, or the Arbiter plays a random legal move. A move sets a marble, then turns any quarter a quarter turn; five in a row wins, for the other side if the turn makes five for it alone, and five for both or a full board is a draw.

Follow the arrows from the rules to this page. standards holds the rules and the reusable workflows that enforce them, called by link and never copied, so a fix lands once and reaches every repository pinned to it. path is the template every new repository starts from, already wired to those workflows. A repository that wants a drawn README adds one markdown stub. Once a day the kit it calls measures the repository, or here the account, redraws what moved and commits it as SVGs, header to footer in one commit, so nothing on this page depends on a third-party service.
