Operations manager turned data engineer. Twenty years running capital construction and telecom infrastructure in the field — now building the data systems that run underneath it.
Most construction data is not in a database. It's in bid PDFs, estimate spreadsheets, permit portals, and submittal logs, written by people who assumed a human would read it. I build the pipelines that turn that into validated, queryable records with provenance intact — because in this domain, an extraction you can't trace back to a page number is not an answer.
Currently — Founder, Armstrong Solutions Inc. (Denver, CO). AI and data automation for the construction industry.
Selected work
| mario | Engineering discipline for AI coding agents. A kickoff gate that blocks code until scope is settled, and a plan → build → review chain where each agent is restricted by tool permissions to what its job needs. The architect physically cannot write files. |
| permit-portal-case-study | How a production permit system collapses ~25 Colorado jurisdictions and ~75 live permits into one queryable record. Architecture and decisions; source private because it holds client data. |
| guild-portal | A place for AI Builders Guild members to share what they're building and get real feedback. |
| nexus-agent-os | Claude command center — agent mission-control dashboard. Next.js, Tailwind, Framer Motion. |
Client systems stay private — the permit portal above is written up as a case study instead.

How I work
Route by task — reasoning-heavy design, bulk implementation, and cheap high-volume classification are different jobs and shouldn't run on the same model. Review by a different model than authored the code. Human approval gates on anything that leaves the building; nothing auto-posts.
