Freelancer Overview

I am an analytical and detail-oriented professional with hands-on experience in data annotation and AI training, specializing in evaluating large language models (LLMs) for accuracy, reasoning, and instruction adherence. My background in environmental engineering and ongoing data science coursework have equipped me with strong skills in Python, SQL, Pandas, and data visualization tools, allowing me to design and apply structured evaluation rubrics and annotate complex data environments. I am committed to ensuring ethical AI alignment and high-quality training data, with a proven ability to identify model failure modes and support human-in-the-loop workflows for continuous model refinement. My diverse technical background enables me to translate data-driven insights into actionable improvements for AI systems.
