Labeling Experience

AI Prompt Engineer and Data Contributor

OtherTextPrompt Response Writing SFT

As an AI Prompt Engineer and Data Contributor, I tested and evaluated AI model responses for quality and failure analysis. I engineered and refined prompts, creating diverse prompt-response pairs for model fine-tuning datasets. My work supported the continuous improvement, safety, and alignment of language models. • Rated and reviewed outputs for accuracy, coherence, and alignment. • Documented evaluation results to identify model inconsistencies and improvement areas. • Contributed to training datasets across various subject domains and complexities. • Practiced independently with diverse prompt structures and instructions.
