Labeling Experience

AI Data Trainer & Prompt Engineer

TextPrompt Response Writing SFT

As an AI Data Trainer & Prompt Engineer at Defined.ai, I designed and optimized prompts to improve language model responses. I annotated, structured, and evaluated datasets to support NLP and conversational AI model training. My work required iterative testing, prompt refinement, and quality assurance to uphold high data standards. • Developed, tested, and refined LLM prompts for greater response accuracy and relevance. • Annotated and structured conversational and textual datasets for model training. • Assessed AI-generated outputs against established quality rubrics for accuracy and tone. • Conducted quality assurance checks to ensure data integrity and safety.
