What I'm looking for

I’m looking for language-data and annotation work—audio transcription, multilingual translation, and text evaluation—where strict guidelines, confidentiality, and accuracy are non-negotiable, and my focus on data quality can directly improve AI training outputs.

I’m a detail-oriented linguistics graduate with professional experience in data annotation, audio transcription (speech-to-text), multilingual translation (English ↔ Yoruba), and language evaluation/error detection for AI and machine-learning systems. I follow strict guidelines closely, maintaining accuracy, consistency, and confidentiality while working with large volumes of language data.

In recent roles, I transcribed audio into accurate text for AI training datasets, ensuring correct grammar, punctuation, spelling, and speaker intent across varied accents and audio quality. I’ve also translated cooperative law documents from English to Yoruba while preserving legal meaning, tone, and cultural context, and I reviewed content for clarity, grammar, factual accuracy, and editorial standards—working independently under tight deadlines with strong time management and data quality assurance.
