I’m a detail-oriented data annotation specialist and video reviewer based in Lagos, Nigeria, with hands-on experience labeling video footage for AI training. I break down episodes into atomic, event-based human actions and apply precise bounding box and polygon annotations while working inside audited QA pipelines that use IoU-based accuracy scoring and guideline consistency checks. I’m also comfortable with de-identification work (blurring/redacting faces and sensitive identifiers) and with dispute/sampling review workflows to ensure labels meet strict thresholds. Alongside my annotation work, I have strong written English, high typing accuracy, and experience as a transcriptionist, content writer/translator, and freelance contributor—so I can communicate clearly in remote, deadline-driven environments.…I’m a detail-oriented data annotation specialist and video reviewer based in Lagos, Nigeria, with hands-on experience labeling video footage for AI training.
