About

Hi, I’m Juliet Eleazu Lagos, and I’m an AI Evaluator with 5 years of hands-on experience reviewing and improving AI model responses and datasets. I focus on finding issues early—like hallucinations, factual errors, unclear wording, and safety or guideline problems—so teams can ship more reliable AI.

I also bring strong data QA and annotation experience, including RLHF-style evaluation, response ranking, moderation flag reviews, and cleaning/tagging text for training. I enjoy testing prompts to see where models break, writing clear feedback for developers, and using tools like Jira and spreadsheets to keep quality high and deadlines on track.
