Freelancer Overview

During my NYSC service at NAFRC, I functioned as a data-driven quality controller — collecting, recording, and interpreting production data across 500+ batches; identifying process deviations; and maintaining zero-error compliance documentation. I also served as a technical instructor for 100+ personnel, which required me to evaluate the clarity and accuracy of information being communicated and adjust it based on audience response. This is directly parallel to AI output evaluation and quality annotation work. Separately, my role as a Data Personnel on the EMID COVID-19 Vaccination Programme involved capturing and validating structured health data for over 3,000 individuals using a digital platform, with an emphasis on data integrity, consistency, and accuracy under real-world field conditions. Beyond fieldwork, my background as a chemistry graduate with strong analytical and research skills, combined with my current work as an independent contractor with RWS on Meta-related AI data projects, positions me at the intersection of domain knowledge and AI training data. I bring subject-matter expertise in science and technical content, bilingual English proficiency at a distinguished level, and hands-on experience in content evaluation, editing, and quality review. The ability to assess factual accuracy, identify inconsistencies, and apply structured judgment to complex content is precisely what sets me apart.
