Freelancer Overview

I am a detail-oriented Data Annotation and AI Training Support professional with over 10 years of experience in data collection, data entry, content management, online research, and quality documentation. My background includes working with research institutions and digital operations where accuracy, consistency, and data validation were essential. I have hands-on experience handling large datasets, organizing and verifying information using Microsoft Excel, conducting field and online research, maintaining records, and supporting content management processes. My ability to follow guidelines carefully and deliver high-quality work has helped me perform effectively in both independent and team-based environments. What sets me apart is my strong attention to detail, adaptability, and ability to work efficiently in remote settings. I have supported research data evaluation projects at the International Institute of Tropical Agriculture (IITA) and managed digital product content and operational records for online business platforms. My experience in content organization, documentation, customer support, and administrative coordination has strengthened my analytical thinking and problem-solving skills, making me well-suited for AI training, data labeling, content evaluation, and quality assurance projects.
