Key Skills

Freelancer Overview

I am a senior statistician and AI training data specialist with over 15 years of experience in applied statistics, biostatistics, and machine learning, including more than 4 years dedicated to generative AI model evaluation and prompt engineering. My work focuses on designing advanced prompts, developing rigorous scoring rubrics, and reviewing thousands of AI-generated solutions for statistical and machine learning tasks. I am highly skilled in Python (Pandas, NumPy, SciPy, Statsmodels, Scikit-learn) for building reference implementations, automating evaluation workflows, and ensuring data quality. My experience spans domains such as healthcare analytics, marketing, and operations, and I have consistently improved model correctness and evaluation consistency in remote, asynchronous environments. I excel at writing clear, step-by-step explanations, creating comprehensive annotation guidelines, and collaborating with cross-functional teams to deliver high-quality AI training data.
