Freelancer Overview

I am an analytical chemistry specialist with over 20 years of experience in laboratory research, method development, and scientific evaluation, including hands-on work with data labeling and AI model training for analytical workflows. My expertise spans mass spectrometry, chromatography, spectroscopy, and quantitative analysis, with a strong foundation in designing reproducible testing protocols, documenting error traces, and developing technical rubrics for model reasoning validation. I have created and verified analytical chemistry prompts, captured model reasoning errors, and provided clear, step-by-step scientific explanations to improve AI systems. My background includes supporting digital workflows, automating analytical interpretation, and ensuring rigorous QA/QC standards, making me well-versed in both technical and evaluative aspects of AI training data for scientific and regulated domains.
