Freelancer Overview

I am a detail-oriented data labeler and AI training data specialist with hands-on experience in text, image, and audio annotation for machine learning projects. My background includes working remotely on diverse projects where I labeled and categorized data, reviewed and edited transcriptions, and evaluated AI-generated outputs for accuracy and quality. I am skilled at following complex guidelines, maintaining consistency in large datasets, and delivering high-quality results within tight deadlines. My strong English proficiency, attention to detail, and ability to work independently make me well-suited for roles in data annotation, quality assurance, and AI model evaluation.
