Systems thinking, applied to AI.

30 years turning ambiguous, high-stakes manufacturing problems into clear, data-driven decisions. Now applying the same rigor — structured decomposition, root cause analysis, and precise communication — to AI training, evaluation, and annotation work.

What I bring

Structured Problem Decomposition

Breaking ambiguous, high-stakes problems into clear, solvable components — the same skill that turns a vague prompt into a well-defined task.

Root Cause Analysis

Six Sigma Black Belt training applied to real production systems for 30 years — finding the actual cause, not the first plausible explanation.

Data Interpretation & Insight Generation

Turning large, messy operational datasets into structured, decision-ready insight, consistently and under real deadline pressure.

Decision Modeling Under Uncertainty

Building frameworks for making sound calls when the inputs are incomplete or contradictory — a constant in manufacturing, and in evaluating AI output.

Analytical Communication

Writing and presenting findings so a technical or non-technical audience can act on them immediately, with no follow-up questions needed.

Pattern Recognition in High-Variability Systems

Spotting the signal inside noisy, high-volume systems — the same instinct needed to evaluate model behavior across many edge cases.

Experience

2016 – Present
Des Moines, IA

Senior Industrial Engineer

Firestone (Bridgestone)

  • Analyze complex, interdependent manufacturing systems to identify variability drivers and performance gaps.
  • Design KPI architectures (OEE, scrap, downtime, throughput) that improve diagnostic transparency across the plant.
  • Build Power BI dashboards integrating multi-source data to make operational performance interpretable at a glance.
  • Apply statistical and logical methods to find root causes and implement corrective actions that actually hold.

Foreman, Operations Leadership

Firestone

  • Led 24/7 multi-line operations spanning people, machines, and material flow.
  • Designed real-time visual management systems that reduced complex operational states to clear, actionable signals.
  • Built a real-time “10-second overview” system for rapid state assessment and decision-making.
  • Standardized cross-shift communication and reporting to cut ambiguity and improve execution consistency.
2007 – 2010
Des Moines, IA

Quality Assurance Engineer

Firestone

  • Ran structured process audits to identify defects, variability sources, and compliance gaps.
  • Led Six Sigma projects focused on complexity reduction and defect elimination.
1996 – 2007

Production Supervisor

Firestone

  • Managed production performance across multiple departments against quality, safety, and output targets.
  • Applied structured problem-solving to reduce operational waste and improve efficiency.
1983 – 1989

Section Chief

United States Marine Corps

  • Led mission-critical artillery operations requiring precise execution under strict procedure.
  • Managed personnel, logistics, and equipment under high-pressure, high-stakes conditions.
