Remote builder and AI trainer at Grand Kru Technologies.
I came up through technology and spent 10 years in activism and community work, and have been building useful systems since 2001. Public GitHub trail since 2008 (earlier work under trystant). That path still shapes how I work: clear goals, fair evaluation, and tools people can actually use.
These days I split time between shipping software and AI training and evaluation. Reviewing model output, tightening tasks and rubrics, and building systems around that loop.
A long-running example of the activism thread: EBWiki, a community-built record of police violence cases.
