I am an AI data analyst focused on developing and refining large language models with strict safety and performance standards. I specialize in meticulous dataset annotation, quality control, and model evaluation to ensure highly relevant training data and reliable system behavior.
Previously, I worked as a Search Quality Rater, optimizing search algorithms and AI responses by evaluating safety, accuracy, and user intent against proprietary guidelines.
