Labeling Experience

AI Trainer & Data Annotator | Outlier (Scale AI)

TextRLHF

As an AI Trainer and Data Annotator at Outlier (Scale AI), I led efforts annotating and labeling diverse datasets for RLHF pipelines and large language model output evaluation. I performed structured evaluation, labeled training and validation data, and applied feedback to improve model quality. My work spanned prompt evaluation, response scoring, and adherence to quality standards. • Labeled and annotated LLM outputs for text generation, code review, and reasoning. • Applied Issue Classification Guides to assess accuracy, safety, and instruction-following. • Used the Outlier platform and related tools for annotation and evaluation. • Maintained a 95%+ task acceptance rate with consistent quality feedback.
