About

Professional summary

I am a physicist-trained machine learning engineer and data scientist with over ten years of independent and contract experience building applied AI, quantitative systems, and production data products.

I specialize in time-series forecasting, quantitative trading systems, NLP, sentiment analysis, transformer models, retrieval-augmented generation, and structured LLM tool calling. I build the live data, backtesting, evaluation, and execution layers needed to deploy models in production.

My technical background includes Python, Julia, Rust, C++, R, and MATLAB, along with cloud, database, market-data, and desktop application development. I have designed systems for options and futures trading, trend intelligence, clinical question answering, pricing, and forecasting.

I apply rigorous validation practices including chronological holdouts, walk-forward evaluation, leakage audits, shuffled-target sanity tests, cost-aware labels, and PnL-based early stopping. I focus on building systems that are robust under real-world data conditions.

My experience spans quantitative finance, defense and space data engineering, instrument calibration, medical coding NLP, education, casino mathematics, and applied statistics. I am also a veteran and have managed IT environments while teaching physics, advanced mathematics, and computer science.

Career history

Data Scientist / ML Engineer Independent and Contract

I provide independent and contract data science, machine learning, forecasting, trading-system, AI-integration, and defense and space data-engineering services. I rebuilt production trend-characteristics forecasting systems using seasonality, spectral decomposition, and volatility classifiers, and continue supporting large-scale trend-intelligence systems.

I design time-series, sentiment, NLP, and neural-network pipelines for summarization, clustering, featurization, message classification, and supervised learning on large labeled datasets. I have integrated conversational AI and retrieval-augmented clinical question answering, including multi-provider LLM tooling with structured tool calling.

I build institutional market-data pipelines, live broker execution systems for futures and same-day options, options-pricing models, cloud-based mission and lunar measurement pipelines, and instrument-calibration software for bio-aerosol sensors. My consulting also includes game mathematics, paytable simulation, medical coding tools, wage analytics, staffing models, pricing models, and anomalous-trade detection.
