Freelancer Overview

I have hands-on experience in AI training data and data annotation, supporting LLM and MMLLM workflows through accurate labeling, content evaluation, and dataset validation. In my role as an AI Operations Data Annotator, I reviewed and classified large-scale social media data, ensuring compliance with policy guidelines while identifying sensitive or potentially harmful content. My expertise includes head-to-head response comparison, entity verification, and quality assurance, with a strong focus on accuracy and consistency. Certified in AI Operations and Customer Experience, I bring analytical thinking, attention to detail, and the ability to work with annotation tools to improve dataset quality, model performance, and overall AI reliability.
