I evaluate and improve LLM outputs through rigorous AI data training.
United StatesWhat I'm looking for
I evaluate, rank, and improve LLM outputs for truthfulness, accuracy, safety, instruction-following, and conciseness. I create multi-turn prompts and gold-standard responses for SFT datasets while identifying hallucinations, logic flaws, and stylistic errors.
I've also analyzed structured and multimodal datasets, validated ground truth, and built quality-control workflows that improved annotation consistency. My work combines RLHF, prompt engineering, fact-checking, SQL, Python, and careful rubric-based evaluation.
