Selected work

Systems with evidence behind them.

Five products spanning agent security, research, education, medical imaging, and hardware design. Every case study separates what works today from what remains in progress.

Experience / selected chapters

Work that survives contact with reality.

Founder, founding engineer, and platform builder across agent systems, medical imaging, education, and compliance infrastructure.

  1. Independent

    Founder & Engineer

    Building AI-native products at the intersection of multi-agent systems and real-world deployment. Currently leading Monkeyclaw and advising two seed-stage AI companies on agent architecture and evals.

    • Designed and shipped a multi-agent security platform from zero to closed beta in 9 months.
    • Advised portfolio companies on agent eval methodology, reducing hallucination-related incidents by 60%.
    • Published an open-source agent capability framework adopted by 800+ developers in the first quarter.

  2. Nexarad (Acquired)

    Founding ML Engineer

    Joined as the second engineer and built the core inference pipeline for a regulatory-cleared medical imaging triage system. Took the model from research prototype to FDA submission.

    • Architected the inference pipeline serving 90-second median time-to-triage at 99.95% uptime.
    • Led the data engineering effort to ingest and de-identify 2.4M studies across 38 institutions.
    • Owned the regulatory ML documentation package that secured FDA 510(k) clearance in 11 months.

  3. Flowe

    Founder & CEO

    Founded and led an adaptive learning company serving community college students. Built the mastery model, raised a pre-seed, and ran a 1,200-student pilot that outperformed control by 0.41σ.

    • Raised a $1.8M pre-seed from education-focused investors.
    • Designed and ran a 1,200-student randomized pilot with a state community college system.
    • Open-sourced the Bayesian mastery model, which has since been forked by 6 university research labs.

A working philosophy

Research taste. Production instincts.

“I build at the intersection of engineering and intelligence—then stay for the hard part: making the system trustworthy, useful, and real.”

I care about multi-agent systems, humane AI, and tools that compound impact rather than extract attention. Most of my work sits in the awkward space between research and production — taking ideas that work in a paper and making them work under a pager.

I'm currently based between Los Angeles and Santa Cruz, splitting time between independent founder work and advising a small number of AI companies on agent architecture and evaluation.

01

Systems over demos

I care about the runtime, the failure modes, and the path from a promising prototype to dependable software.

02

Evidence over theater

The strongest product story is a working system with visible constraints, measured outcomes, and honest boundaries.

03

Human agency first

AI should make people more capable without making the decisions, provenance, or consequences harder to inspect.
