Brad M. Lindsey
Independent engineer · Master Electrician · Master HVAC Technician
I spent twenty-plus years in the trades — switchgear, BAS, VFDs, federal facilities, the kind of work where what's behind the wall has to actually do what the paperwork says. On April 4, 2026 I started writing my first lines of code.
By May 2026 I had produced roughly 280,000 lines of Python in cumulative authorship across several research and product trunks, all written collaboratively with frontier LLMs. None of that volume is impressive on its own. What's interesting is what I had to figure out along the way to keep it honest.
I build small, careful software with cryptographically-auditable provenance. The discipline is open-source. The buyer for the consulting that comes with it is a mid-market engineering team adopting AI-assisted development and now noticing the drift, claim inflation, and lost-provenance problems that come with it.
What I'm building
-
Lindsey Provenance DisciplineOpen-source methodology framework for disciplined LLM-collaborative engineering. Phase-chain freeze, six-state proof-state ledger, closed-form re-route at intake, seven-phase multi-modal brief assimilation. MIT licensed.

Expert data & model evaluation
AI labs and data vendors pay domain experts to produce calibrated training and evaluation data — RLHF preference ranking, expert annotation, red-teaming, model evaluation in regulated technical fields. I'm available for that work, per-project or ongoing.
The profile is specific: twenty-plus years as a Master Electrician and Master HVAC Technician — switchgear, BAS, VFDs, NEC compliance, federal facilities for the Department of Defense and Defense Health Agency. PMP. The credential is public; the facility specifics are not. And — unusually for a tradesman — I work daily with frontier LLMs under cryptographically-auditable provenance.
That last part is the difference. A licensed tradesman who can rank model outputs is useful. A licensed tradesman who hands you provenance-anchored expert data — every claim tagged to its proof-state, every authorship step signable against the key in the footer below — is rare.
