As a freelance data annotator and AI data quality reviewer, I annotated and reviewed a variety of datasets for AI training and evaluation. I specialized in text classification, preference comparison, and LLM response assessments to ensure data quality and compliance with guidelines. My role also involved using Python scripts for cleaning and validation, supporting a high volume of accurate annotations. • Labeled and reviewed over 20,000 data items for classification, entity tagging, and response evaluation. • Compared and ranked model outputs to identify higher-quality responses and flag ambiguous cases. • Ensured 95%+ QA accuracy by strictly following detailed guideline instructions. • Automated mundane data review and cleaning steps using lightweight Python tools.
