AI Content Reviewer & Data Annotator

OtherTextClassification
As an AI Content Reviewer & Data Annotator for Handshake and other platforms, I ensured outputs met detailed quality, safety, and relevance criteria through thorough review and scoring. I performed binary and multi-class labelling for content moderation and harmful content detection tasks, applying nuanced judgment to ambiguous examples. I consistently met daily throughput requirements while adhering to strict quality service levels. • Content moderation and topic classification for AI-generated materials • Multi-class, binary, and relevance scoring on ambiguous and adversarial cases • Application of detailed annotation guidelines and platform-specific SLAs • Output review for quality assurance across legal, safety, and general knowledge domains
