> AI Engineer | Energy Industry | Greater Houston_

AI Engineer with 5 years of experience building production AI/ML systems for the energy industry. I architect agentic RAG systems, predictive ML pipelines, and compliance automation that run in enterprise environments.

class AIEngineer:
    def __init__(self):
        self.focus = [
            "Agentic RAG & Multi-Agent Orchestration",
            "Predictive Maintenance & Anomaly Detection",
            "MLOps & Production ML Systems"
        ]

    def deploy(self, model) -> Production:
        return model.notebook_to_production()

Ventures

AI-powered knowledge management platform for oil & gas engineers. 7-stage agentic RAG pipeline with human-in-the-loop review, verified citations, and zero hallucinations. Built for corrosion engineers working with ASTM, API, and NACE specifications.

Next.js 16 React 19 TypeScript Claude Sonnet Supabase pgvector Voyage AI Vercel


Production MLOps platform processing 50k+ sensor readings through Bronze/Silver/Gold medallion architecture. PySpark ETL pipelines feed real-time fleet health dashboards with automated drift detection and retraining triggers.
