Freelancer Overview

I have experience working on AI training and evaluation tasks that require attention to detail, accuracy, and strong judgment. My work has involved reviewing model responses, comparing outputs, and rating them based on factors such as instruction following, truthfulness, correctness, writing quality, verbosity, and overall quality. This has helped me develop a careful approach to identifying factual errors, weak reasoning, and differences in response quality. I have also worked on image and video-related annotation tasks, where I described visual content clearly and accurately while following strict guidelines. These tasks required me to focus only on what is visible, avoid guessing, and produce structured, high-quality descriptions. In addition, I have experience with audio-related tasks, including identifying speech, music, and background noise, as well as applying timestamps and concise labeling rules. Through these projects, I have built strong skills in guideline interpretation, quality control, and consistency. I am comfortable learning new project instructions quickly and applying them with precision. My experience has taught me how important it is to balance speed with accuracy, maintain objectivity, and deliver work that supports the improvement of AI systems.
