AI Content Consultant & Annotation Specialist

Text
As an AI Content Consultant & Annotation Specialist, I developed evaluation frameworks and prompt designs to improve AI response quality. My responsibilities included reviewing AI-generated outputs for hallucinations, biases, and inconsistencies, maintaining a high standard of accuracy. I consistently documented annotation decisions and aided in auditability for scalable, accurate evaluation systems. • Developed and refined prompts for generative AI models • Identified tone misalignment, bias, and instruction violations in AI responses • Maintained approximately 99% annotation accuracy throughout projects • Supported dynamic annotation projects under tight deadlines
