Self-Directed Projects

About 13 years self-directedCareer transition began June 2026

• Shipped Flywheel 1.9.0 on PyPI, a Python/Flutter AI workstation with model routing and a Windows installer; its behavior-check caught 20 of 20 planted changes with 0 of 50 false alarms.
• Built test infrastructure for evaluating AI agents: 324 terminal-state fixtures and 337 component cases that separate failed outputs from provider failures.
• Built Articulate 0.16.0 writing analysis, Accountable Surface approval interfaces, BuildLang 1.10.0 capability checks and Phantom audit and restore.
• Built Daylight Commons 3.2.2 (now CMMNS), a browser extension for nine platforms; slur-sign precision 3,995 of 4,392.
• Ran a pinned METR count_odds task through the Inspect-to-Flywheel bridge with three deterministic controls.
