Freelancer Overview

I am a detail-oriented AI Data Annotator with hands-on experience in image, video, and garment annotation, as well as prompt accuracy evaluation for AI training data. I have worked on diverse annotation projects at Hugo Tech and Micro 1, where I ensured high-quality, consistent data labeling to support computer vision and machine learning systems. My expertise includes using tools like Labelbox and SuperAnnotate, performing visual defect detection, and maintaining style and identity consistency across datasets. I am committed to delivering precise, reliable annotations and enjoy collaborating with teams to drive the success of innovative AI projects. My goal is to further develop my skills in data annotation while contributing to the advancement of AI model accuracy and performance.
