AI Data Annotator and LLM Trainer (Freelance)
I provided high-quality human feedback to improve large language models through data labeling and annotation tasks. My responsibilities involved content annotation, evaluation, and prompt response rating to ensure model accuracy and alignment with guidelines. I followed complex instructions while maintaining critical thinking and consistent attention to detail. • Performed sentiment analysis, intent classification, and entity recognition on a variety of text data. • Applied reasoning and chain-of-thought annotation for enhanced LLM evaluation. • Used platforms such as Appen, Lionbridge, Scale AI, Toloka, and custom annotation tools. • Delivered multilingual annotations and maintained high quality across different domains.
