Freelancer Overview

I am an AI Operations Associate with experience in LLM training, data annotation, and content evaluation across text, image, audio, and video. At Hugotech, I contributed to high-impact projects including External Search, Personas UGC, and Taxonomy Use-case, while leading annotation of 50K+ multimodal datasets. My work designing task-specific prompts and evaluating 4,000+ AI outputs improved model accuracy, reduced hallucinations, and enhanced overall system reliability. One of my standout contributions was on video captioning projects, where I meticulously annotated short-form clips to capture key actions, camera movements, and scene details. In a fast-paced, performance-driven environment, I consistently exceeded quality standards and supported team success by reviewing and refining peer outputs. With a strong foundation in ethical AI, bias mitigation, and analytical problem-solving, I bring precision and reliability to building effective and trustworthy AI systems.
