Freelancer Overview

I am a detail-oriented Data Annotation Specialist and AI Training Contributor with hands-on experience across multiple leading platforms, including Toloka, Appen, Clickworker, and SigmaAI. My work spans diverse data labeling tasks such as text classification, sentiment analysis, image and video annotation, conversational AI evaluation, and reinforcement learning from human feedback (RLHF). Fluent in both English and Yoruba, I contribute to multilingual NLP projects and am adept at curating datasets for machine learning in various domains. My strong analytical background in Economics, combined with fast and accurate typing skills, allows me to consistently deliver high-quality annotations while meeting strict deadlines. I am proficient in Microsoft Office, Google Sheets, and online survey tools, and have participated in research and user experience projects for both academic and commercial clients. I pride myself on my attention to detail, reliability, and ability to work independently on complex tasks.
