About

I’m a highly analytical, detail-oriented bilingual AI Training Specialist and Language Consultant with native fluency in Yoruba and professional mastery of English. I help ensure localized AI systems achieve cultural, contextual, and syntax accuracy for Yoruba-English use cases. I bring proven expertise in data labeling, linguistic annotation, and Reinforcement Learning from Human Feedback (RLHF). In my freelance work, I review, score, and fine-tune machine-generated responses for Large Language Models (LLMs) using strict criteria—accuracy, factual consistency, safety, and cultural relevance—while performing complex multi-turn prompt engineering. Previously, I supported high-stakes operations as a Technical Operations Specialist, using advanced diagnostic software and rigorous technical logs to optimize workflows and generate analytical summaries. I also taught and trained learners as a Technical Instructor/Class Teacher, translating complex technical and scientific ideas into structured learning modules—an approach I apply to clear, consistent annotation and evaluation.
