Freelancer Overview

I am a detail-oriented aspiring AI Trainer with hands-on experience in data labeling, annotation, and quality assessment for natural language processing projects. Through my recent freelance AI training project, I conducted data labeling on over 100 text prompts, ranked AI responses based on helpfulness and coherence, and analyzed large language model outputs to identify factual errors and stylistic inconsistencies. My approach emphasizes meticulous attention to detail, strong analytical thinking, and strict adherence to project guidelines. I am passionate about improving model accuracy and ensuring AI outputs are helpful, honest, and unbiased. With strong writing and research skills, I am eager to contribute to high-quality AI training data and support the development of reliable language models.
