Freelancer Overview

I have extensive experience in AI training data projects, specializing in text evaluation, linguistic accuracy, and content quality assurance. Over the past few years, I have worked on multiple large-scale annotation programs with companies such as RWS and TrainAI, focusing on areas like hallucination detection, prompt evaluation, and user intent classification. My background in history and philosophy allows me to approach data labeling with strong analytical reasoning, ethical awareness, and contextual understanding—skills essential for evaluating nuanced or culturally sensitive AI outputs. In addition to linguistic and analytical work, I bring a solid foundation in data analytics and quality control. I am comfortable using structured labeling platforms and following detailed project guidelines with high precision. My interdisciplinary training enables me to bridge technical and conceptual domains, ensuring that every dataset I contribute to supports both accuracy and meaningful AI model improvement.

LLM Evaluation and Prompt Quality Rating Project

Internal Proprietary ToolingText
I participated in multiple large-scale AI evaluation and data labeling projects for natural language models. The tasks involved assessing LLM outputs for accuracy, relevance, factual consistency, and ethical compliance. I performed prompt-response evaluations, hallucination detection, and comparative rating (SxS) following strict quality guidelines. Each project required consistent attention to linguistic nuance, contextual understanding, and adherence to rating rubrics. I maintained a high-quality score and met all AET (Average Evaluation Time) and consistency standards. These projects contributed to improving large-scale AI models used for global applications, emphasizing human alignment and responsible AI development.
