What I'm looking for

I’m looking to grow in AI data operations—auditing LLM outputs, optimizing prompts, and building high-quality multimodal datasets—while partnering with a detail-driven team that values safety, accuracy, and measurable quality.

I’m a versatile AI/LLM Data Analyst with experience in AI data annotation, model evaluation, prompt optimization, and search engine assessment. In my current role, I audit AI-generated outputs for factual accuracy, safety, bias, and brand alignment using RLHF methodologies, while also annotating and labeling multimodal datasets (text, image, audio) for AI training and quality assurance.

Before that, I strengthened my evaluation craft as a Senior Data Reviewer & Quality Specialist, ensuring compliance with annotation guidelines and identifying inconsistencies and errors in labeled datasets. Alongside my AI work, I bring a strong education background as an ESL/IELTS Teacher and an AI Prompt Tester/Engineer, plus SEO experience using WordPress, Webflow, Squarespace, Ahrefs, SEMrush, and Google Keyword Planner—so I can translate analytical detail into clear, actionable improvements across technology and content.
