Engineer · AI Agent Builder

Engineer-grade discipline for building AI agents for lending and real estate.

18+ years turning root-cause analysis and process control into results. First on automotive launch lines for VW and GM, then in mortgage operations. Now I build AI agents that help lenders, loan officers and realtors move faster with fewer errors.

Four pillars

One method. Four arenas.

The same discipline that took airbag lines to zero defects now runs my AI agents, my mortgage files and my trading research.

AI Agents & Governance

I build AI agents for lenders, loan officers and realtors, and agent systems for other businesses, with governance designed in from day one.

  • 9-agent marketing pipeline: web, leads, social, funnel, nurture
  • Governance playbook on Harvard HDSI's S.T.E.E.R. framework
  • Mapped to NIST, the EU AI Act and financial services rules

Systematic Trading R&D

Research and development of rule-based trading systems grounded in Auction Market Theory. A work in progress, not a service or a track record.

  • Research areas: Market Profile, value area, Initial Balance
  • Supply and demand imbalances, VWAP, statistical averages
  • Dealer gamma positioning and market structure
  • Testing on gold futures (GC) and equity-index futures

The method

From the plant floor to the closing table

Every arena runs through the same five-step loop. Only the data source changes.

STEP 1

Measure

Collect clean data before forming an opinion.

AI Agents: lead flow, close rate, cost per loan
Plant: SPC, MSA
Market: TPO, volume, gamma
STEP 2

Find the cause

Separate signal from noise. Ask why until the answer stops changing.

AI Agents: too few leads, slow follow-up
Plant: 8D, Ishikawa
Market: auction context
STEP 3

Write the rule

Turn the finding into a rule anyone can follow the same way twice.

AI Agents: agent workflow with guardrails
Plant: control plan
Market: playbook
STEP 4

Execute

Follow the rule with fixed risk. No improvising mid-process.

AI Agents: 24/7 agents, human sign-off
Plant: work instructions
Market: sizing, stops
STEP 5

Review

Audit results against the standard and close the loop.

AI Agents: KPI dashboard, audit log
Plant: process audit
Market: journal, expectancy
Daily field notes
