Freelancer Overview

I am a Data Annotator with over three years of experience supporting AI training and data labeling projects in remote, quality-driven environments. My work has focused on handling diverse data types including video, image, and document datasets while following structured workflows and strict quality standards. I have hands-on experience with annotation tasks such as action recognition, bounding box creation, and data collection, ensuring accurate and consistent datasets for machine learning applications. I also use tools like Google Sheets to manage tasks, track progress, and maintain organized, reliable outputs. I hold a Bachelor of Science degree from the Federal University of Technology, Owerri (FUTO), which supports my strong research, analytical, and detail-oriented approach to annotation work. My background in complex workflows, combined with a commitment to accuracy and confidentiality, enables me to deliver high-quality labeled data that helps improve AI model performance.
