Case studies

Seven projects, five of which you can open right now.

Each write-up covers the problem, the calls I made and why, how the result was measured, and where the evidence stops. Five link out to a live artifact you can check against what is written here.

Case study · CRE bridge lending

Founding the AI function at a regulated lender

Two services were live in production at handoff, including a daily investor-enrichment pipeline, on a governed platform where nine departments could publish reviewed, drafts-only skills (agents propose, humans send). Two months, one engineer, on contract.

Pipeline diagram: public sources, quality gate, depth-scored research, draft, then CRM, rep tool, and a named human who sends. A crossed-out line marks the send path that does not exist.

CRE lending · production service

An enrichment service that researches like an analyst and never sends

A service that ran daily in production: research a live investor cohort from public sources, score its own research, draft the outreach, and write it to the CRM for a named human to send. The system sent nothing, by design.

Case study · Mars veterinary diagnostics

Agentic engineering at enterprise scale

Agents that diagnose live production incidents, review pull requests, and draft the change-control paperwork behind a deploy, inside a Mars business running 50,000+ diagnostic orders a day. Production MTTR went from weeks to under 24 hours, and every other number here carries the methodology behind it.

Case study · Regulated fintech / DeFi

Crypto custody, and recovering $4M+ in stranded creditor assets from 5M+ vaults

AI platform work paired with a decade of institutional custody and DeFi architecture: CCSS Level 3 custody at Vellum, wrapped-token launches, and $4M+ recovered for creditors during the Celsius bankruptcy.

Case study · Public, one-person agentic system

A governed agentic pipeline you can audit end to end

A collection of 160+ interactive reference pages, built and maintained by one person plus AI agents, held to one written spec and shipped through a human merge gate. The pipeline is the thing worth looking at: it makes the next page cheap and consistent, and every commit is browsable in public.

Case study · Public agentic system

A civic data reference built in a day, and kept current by agents

Built inside a day from a paragraph of intent, then kept current by six pull-request-only agents behind a human merge gate. Every published fact carries its source, the date it was checked, and who verified it.

Case study · Public evidence reference

A graded, sourced reference on who pays for AI

A public reference site that grades who actually bears the cost of the AI infrastructure buildout: electricity, water, grid equipment, and memory. Every number carries a primary source and two dates, published and last checked, and one person plus AI agents keeps it current.
