## About

Are you making critical business decisions based on weak research frameworks or messy data? With 20+ years across academia and advanced defense contracting (AFRL Human Performance Wing), I step in as a hands-on individual contributor to secure your statistical validity. Whether you are a startup launching a user survey, a product team running A/B testing, or an enterprise validating predictive AI models, I eliminate guesswork and replace it with absolute mathematical proof.

Expertise You Can Book Me For:
• Study Architecture: Designing bulletproof behavioral, consumer, or product experiments from scratch.
• Survey Engineering: Drafting unbiased questionnaires, psychometric scales, and complex skip-logic.
• Data Wrangling & Analytics: Cleaning disparate user logs, clickstreams, or telemetry datasets.
• Advanced Modeling: Running linear mixed-effects, regressions, and forecasting models (R, Stata, SPSS).
