Labeling Experience

Freelance AI Data Labeling & Content Review

Text
As a freelance AI Trainer and Data Labeler, I reviewed and compared AI-generated responses for relevance, tone, and instruction-following. I performed text annotation and data labeling tasks primarily in Spanish to support AI training and evaluation. I applied strict attention to detail while ranking outputs and identifying inconsistencies in quality and formatting. • Ranked multiple AI responses based on set quality criteria • Annotated Spanish text data for instruction-following and content correctness • Conducted content quality analysis for RLHF and prompt evaluation • Worked independently using online annotation platforms and data review dashboards
