Freelancer Overview

I am a detail-oriented AI data annotation and training professional with hands-on experience in image, video, and text labeling projects. My work includes evaluating AI-generated outputs for accuracy, relevance, and prompt adherence, as well as annotating diverse data types to support machine learning model development. I am skilled in applying quality control standards, conducting comparative analysis, and providing structured human feedback to enhance dataset reliability. With a strong background in data administration and digital documentation, I consistently maintain high accuracy and follow strict guidelines across repetitive workflows. I am adept at using tools like Google Workspace and Microsoft Excel, and I thrive in remote environments where precision and consistency are essential.
