Freelancer Overview

I am a native Yoruba speaker with advanced English proficiency and over three years of hands-on experience in AI data annotation, content evaluation, and linguistic tasks. I started with translation and tutoring work in 2023, then moved into professional AI data projects where I label images, evaluate text outputs, and annotate audio data. I am very detail-oriented and good at following complex guidelines while maintaining high accuracy. My experience includes working on image labeling at ABAKA AI, text and response evaluation at Appen, and Yoruba language data projects at TELUS International AI. I’m passionate about contributing high-quality data that helps improve AI models, especially for multilingual and African language use cases.

My tasks included comparing generated images against specific prompts, making pass/fail judgments based on strict guidelines, and ensuring visual quality, relevance, and consistency. I maintained high accuracy while working independently on large volumes of data.
