AI Data Trainer/AI Model Evaluator

As an AI Data Trainer and Model Evaluator, I annotated and evaluated large language model (LLM) outputs for quality and precision. My tasks included assessing prompt-response pairs, identifying errors, and providing detailed feedback in remote environments. I also contributed to the development and refinement of training datasets and annotation guidelines. • Evaluated AI-generated text responses for accuracy, safety, and instruction adherence. • Annotated datasets specifically for LLM and machine learning model training. • Detected hallucinations, logical inconsistencies, and domain-specific inaccuracies. • Collaborated cross-functionally to improve annotation protocols and dataset quality.
