Justin F.
Operations & Manufacturing Guru (25+ Yrs) | AI Trainer (RLHF)
I don’t just "consult”, I bridge the gap between complex industrial reality and high-level technical execution. I spent 25 years climbing from an apprentice operator to a Senior Operations Leader, culminating in the successful launch of a major Greenfield manufacturing facility. My career has been defined by fixing what’s broken; whether it’s a $14M P&L, a "preferred supplier" status on the brink of collapse, or a training program stuck in the 1990s. Today, through Ground Truth Logic LLC, I provide two distinct, high-value services for clients who cannot afford hallucinations or operational drift: 1. Operational Excellence & 'Ground Truth' Standardization Most "standard" operating procedures are neither standard nor operational. I specialize in auditing legacy systems (MOC, SOPs) and modernizing them for the current workforce. * Workforce Evolution: I solve the "Gen Z engagement gap" by re-architecting apprenticeship and training programs to move away from tribal knowledge and toward scalable, logic-based workflows. * Process Engineering: Lean Six Sigma (Green Belt) methodology applied to real-world constraints. I’ve led 80% reductions in downtime through SMED and stabilized distressed facilities facing 13%+ reject losses. * Asset Management: From SAP/ERP implementations to PM/PdM strategies that extend asset life years past their cycle. 2. AI Training & Technical Domain Expertise (RLHF) The biggest bottleneck in generative AI is the lack of "Ground Truth" for specialized industries. I leverage 25+ years of manufacturing domain expertise to train, audit, and refine Large Language Models (LLMs). * Technical Validation: I execute rigorous, rubric-based evaluations of AI outputs to ensure safety compliance, factual accuracy, and strict adherence to industrial context. * High-Fidelity Prompt Engineering: Designing multi-step tasks that train models on occupation-specific workflows, ensuring zero hallucinations in high-stakes environments. * RLHF Specialist: I serve as the human-in-the-loop for Reinforcement Learning, providing the "expert feedback" necessary to move a model from generic chat to professional-grade tool. 3. Career Highlights & Proven Results * Greenfield Leadership: Recruited as a founding leader for a major facility launch; exceeded production ramp-up projections by 20%. * Turnaround Success: Restored "Preferred Supplier" status for a high-volume facility by correcting batch logic and standardizing inputs. * Financial Stewardship: Managed $14M+ operating budgets, consistently delivering under-budget performance while exceeding realization of maintenance spend. Why work with me? Because I’ve been the guy at the 2:00 AM breakdown, and I’ve been the guy in the boardroom explaining the P&L variance. Whether you need to fix a failing production line or ensure your AI model knows the difference between a minor variance and a catastrophic failure, I provide the logic that grounds the project.
