Air Force Cost Analysis Agency (AFCAA)

Professional Summary

I am a Data Scientist and Operations Research Analyst with over a decade of experience bridging the gap between rigorous statistical theory and frontier-tier AI implementation. My career has been defined by high-stakes environments—from conducting $20B+ cost assessments for the Air Force to building NLP-driven clustering models for brands like Chipotle.

I specialize in creating autonomous, self-improving systems that drive measurable business value:

  • Agentic AI & RAG: Architecting multi-agent systems with LangGraph, CrewAI, and LangChain to solve complex, unstructured enterprise problems.

  • Predictive Modeling: Developing high-accuracy models (85%+) for churn, demand forecasting, and cost analysis using Python and R.

  • Strategic Leadership: Leading $20B+ program assessments (TS/SCI Cleared) and mentoring data teams in SaaS and Government sectors.

  • Full-Stack Deployment: Building production-grade data tools and interactive dashboards using Streamlit, R-Shiny, and Databricks.

I thrive at the intersection of predictive analytics and agentic workflows, turning raw data into strategic, autonomous advantages.
