Freelancer Overview

I have 3+ years of experience spanning end-to-end AI training data workflows, including data labeling, response evaluation, and safety-focused rubric design. As a freelancer, my work has included annotating and reviewing text for quality, relevance, and accuracy, as well as creating clear, operational criteria that other annotators can follow consistently. This experience covers tasks such as ranking and scoring model outputs, identifying policy and safety violations, and refining guidelines to increase agreement between other annotators and improve overall dataset quality. ​ In addition, I have substantial experience in safety parameter testing and evaluation for large language models, with a focus on testing edge cases for safety policies and applying real-world user scenarios. This includes drafting and iterating on evaluation rubrics, documenting rationales for complex decisions.
