What I'm looking for

I seek hands-on roles improving LLMs or vision models through precise annotation, rigorous evaluation, and collaborative, quality-focused teams.

I am an AI data contributor and NLP-focused linguistics analyst with hands-on experience in data annotation, model evaluation, and content contribution for LLMs and computer vision projects.

I have contributed to RLHF, model evaluation, safety tasks, and image annotation for clients including Apple, and I regularly provide detailed human feedback to improve model accuracy, fairness, and fluency.

I bring strong linguistic analysis, meticulous attention to quality control, familiarity with annotation tools, and fluency in English and Vietnamese to help teams deliver well-curated training data and reliable model performance.
