I build systems that keep working even after I log off.

Engineering leader by day; builder of a personal automation fleet, a second brain, and small sharp tools by night.

Pragmatic Increments

Durable systems are built in pragmatic increments. I help organizations define their target state, and chart the tactical path to reach it.

Fractional leadership

A senior operator in the room for decisions that are expensive to get wrong.

AI strategy & automation

Integrations and automations that actually ship, backed by a strategy that separates leverage from theater.

Pro bono

Speaking, hackathon judging, and honest current-state assessments.

Work

A personal second brain and automation fleet: a dozen-plus scheduled agents that digest research, groom a knowledge vault, work an overnight queue, and report every morning.

signetnames.com active

A naming tool for people who take names seriously. Built to learn what shipping a consumer product actually feels like.

masters/593 active

Study tools for a computer-systems course, built for a phone. Flashcards that fill only as topics get drilled, each card traceable to the question that produced it.
