What I'm looking for

I seek roles where I can apply rigorous annotation, model evaluation, and search-quality expertise within collaborative teams prioritizing AI safety and measurable impact.

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. I consistently ranked in the top 10% for accuracy and efficiency and regularly provided actionable feedback that improved algorithmic performance.

My background also includes long-term caregiving and customer-facing roles that strengthened my communication, problem-solving, and operational skills. I bring a disciplined, detail-oriented approach and collaborative mindset to cross-functional teams focused on improving AI and search experiences.
