What I'm looking for

I’m looking for remote, quality-focused AI data work where I can evaluate responses, apply annotation guidelines, and improve language understanding for Yoruba and English—especially with human-in-the-loop training, strong standards, and ethical AI practices.

I’m a Yoruba AI Trainer and AI Data Specialist with a computer science background and years of experience in data evaluation, language analysis, and quality assurance. I evaluate AI-generated outputs for accuracy, relevance, tone, and instruction compliance, applying detailed annotation guidelines to ensure consistent, fair results.

I also focus on human-in-the-loop AI training and responsible AI practices—flagging bias, ambiguity, and ethical risks while performing intent and text classification, bias detection, and fact verification. I’ve worked with distributed teams and remote environments, maintaining high quality and productivity while improving AI system behavior through structured feedback.
