Freelancer Overview

I have experience working in AI training data and data labeling, with a focus on evaluating model outputs for quality, accuracy, and instruction-following. I am currently working on the Handshake Hedgehog project, where I review and assess AI-generated responses, compare outputs, and help improve training data quality through careful judgment and consistency. My work involves paying close attention to detail, identifying errors or weak responses, and making decisions based on guidelines, relevance, clarity, and overall usefulness. What sets me apart is my ability to combine strong analytical thinking with patience and consistency. I am comfortable working with detailed instructions, maintaining accuracy across repetitive tasks, and handling projects that require both quality control and human judgment. I am also a quick learner, adaptable to new labeling systems and workflows, and committed to producing reliable, high-quality data that helps improve AI systems.

AI Training Data Evaluator - Project Hedgehog

TextEvaluation Rating
Currently contributing to Project Hedgehog, an AI training data project focused on evaluating and improving model-generated text outputs. My work involves reviewing submitted responses, comparing alternative outputs, and labeling them based on instruction-following, relevance, clarity, quality, and overall usefulness according to detailed project guidelines. This requires strong judgment, consistency, and close attention to detail to ensure high-quality annotations. The project operates under strict quality standards, handling-time expectations, and workflow guidelines, which has strengthened my ability to perform accurate response evaluation in a structured production environment. I work efficiently while maintaining annotation quality, follow project-specific standards carefully, and help support the creation of reliable training data used to improve AI systems.
