Freelancer Overview

I have been working as a freelance AI trainer and evaluator since 2023, contributing to platforms such as Scale AI, Outlier, and DataAnnotation. My work has involved evaluating and ranking LLM responses across expert-level STEM domains — including genomics, machine learning, and data science — for RLHF reward model training. I have written high-quality gold-standard responses used as ground truth for model fine-tuning, and reviewed AI-generated Python and R code for logical correctness, edge cases, and documentation quality. Beyond response evaluation, I have contributed to scientific fact-checking tasks, verifying citations, identifying model hallucinations, and rating response accuracy against peer-reviewed literature. My consistently strong performance placed me in the 95th+ percentile on QA scores, earning me a senior reviewer promotion on two separate projects. This work is further grounded in my 6+ years of deep research experience in bioinformatics and machine learning, giving me strong domain authority in the scientific areas I annotate.
