Freelancer Overview

I am an experienced AI data annotator with expertise in computer vision, multimodal AI, content moderation, and model evaluation. I have worked on diverse projects involving video, image, and audio data, including classification, object detection, segmentation, temporal event annotation, question answering, text generation, and large-scale data collection. My experience includes labeling complex gameplay footage, moderating NSFW content, and creating high-quality training datasets for machine learning models. Beyond annotation, I have extensive experience evaluating AI-generated outputs for quality, prompt alignment, consistency, realism, and safety. I have contributed to projects supporting computer vision models, multimodal systems, and generative AI applications. Known for strong attention to detail, fast learning, and strict adherence to annotation guidelines, I consistently deliver accurate and reliable training data that helps improve AI model performance.
