What I'm looking for

I’m aiming to grow and take on more responsibility wherever needed.

At OTAKU.HUGO Technologies, I annotated text, image, audio, and video datasets for AI model training, including object detection, pixel-level segmentation, 3D tracking, and named entity recognition. I also supported RLHF workflows through preference ranking, response editing, and evaluating outputs for safety and alignment.

As a Campaign Data Coordinator for the 2023 Presidential Election Campaign in Osun State, I managed data for more than 12,000 members, digitized paper records, and built a centralized media database. I’ve also handled data entry, invoice matching, and customer support as a Virtual Administrative Assistant on Upwork.
