Adaku Oparaji

I’m an AI Training Contributor with over 8 years of experience across administrative operations, remote project support, and AI data evaluation. I evaluate complex audio, video, and text datasets to improve the reasoning and safety of frontier AI models.

At Appen (CrowdGen), I annotate linguistic data with 95%+ accuracy and contribute to the localization of search relevance for West African dialects. I’m recognized for consistent high-quality scores in Search Evaluation, which has led to selection for high-priority global annotation projects.

Alongside AI work, I’ve optimized workflows and records to keep teams moving fast in high-pressure environments. As an Administrative Officer at Empire Energy Limited, I reduced document retrieval time by 30% through digital categorization and lowered annual administrative overhead costs by 15% by overhauling supply tracking. Earlier, as a Personal Assistant at Catneiling Ltd, I improved executive productivity by 20% through a digital scheduling protocol, and as a Secretary (Industrial Training), I created a quick-reference filing guide adopted by my unit to train subsequent interns.
