Freelancer Overview

I am an experienced data labeler with a strong background in both text and image annotation. I have contributed to a range of AI training data projects, including LLM safety evaluations, RLHF ranking tasks, grammar annotation, and facial manipulation data collection. My work spans across multiple platforms such as SelectStar, Flitto, CUBox, and others, where I’ve successfully delivered high-quality annotations in NLP, computer vision, and structured data labeling. My strengths lie in linguistic sensitivity, detail-oriented classification, and consistency in large-scale labeling tasks. I have hands-on experience in prompt response ranking, grammar correction, entity tagging, and VLM image labeling. I am confident in managing tasks that require both accuracy and domain understanding. I’m a fast learner, highly reliable, and passionate about contributing to the development of safe and effective AI systems.
