Freelancer Overview

I have hands-on experience in data labeling and AI training support through 800+ hours of freelance research and annotation work on Upwork, where I maintained a 97% accuracy rate across 50+ projects. My background includes digitizing and verifying 5,000+ government records, categorizing datasets for machine learning models, and flagging policy violations with precision. I am proficient in following detailed annotation guidelines, delivering consistent feedback, and working independently with minimal supervision. What sets me apart is my Computer Science degree combined with Google Data Analytics and Machine Learning certifications, which give me a solid technical foundation to understand the context behind the data I label. My experience in customer support and tutoring has strengthened my communication skills and ability to provide clear, constructive feedback essential for RLHF and model evaluation tasks. I am fluent in English and Igbo, detail-oriented, and available 12–15 hours per week with a flexible schedule.
