Applied AI

Technologist in Residence at Nava PBC · Former U.S. Digital Service, Slalom, Ibotta, JazzHR

Available for New Opportunities

Technology leader in applied AI for benefits and public services, with 15 years of experience scaling teams and shipping production systems. Technologist in Residence at Nava PBC, where I lead the Nava Labs prototyping squad. My research tests AI against ground truth that can be checked — benefit formulas defined in statute, small models that run on the device, and evaluations with gates set before the runs. Previously led engineering at Department of Veterans Affairs Office of the CTO (USDS) and high-growth startups.

Weight-Space Programming for the Social Safety Net

An independent test of the claim that AI models can write, read, and edit neural network weights directly, run against US benefit formulas where the correct answer is defined by law. Written weights were exact. Trained weights failed in ways average accuracy hides. And one step of the law cannot be represented at all.

Nine Versions of a Redaction Model

I trained my first model to redact PII and PHI on-device: an 11-million-parameter token classifier that fits in 11.3 MB. Nine versions of synthetic data, strict span scoring, and a failure ledger got it to 0.974 full-value recall on my golden set, with the misses still named in the post.

phi-redact

An 11M-parameter model that finds PHI and PII - patient names, MRNs, dates, phone numbers and 26 other types - in English text, small enough to run in the browser so the text never leaves the device. Roughly tied with Desert Ant's Redact on English recall at half the size.
