I’m a video annotation specialist and AI data annotator based in Benin City, Nigeria, with hands-on experience reviewing first-person/egocentric video, doing frame-level labeling, and maintaining high-quality ground-truth datasets. I also evaluate AI-generated descriptions and responses by comparing them against the source content, task requirements, and rubrics, then clearly flag inaccuracies or instruction-following issues. Alongside annotation work, I’ve developed strong technical and analytical skills using Python, Pandas, Excel, SQL, and web basics, and I’ve supported process consistency by improving workflows and creating onboarding guides for new annotators. With an academic background in Biochemistry and professional experience in analytical and clinical laboratory environments, I bring careful attention to detail, factuality validation, and quality-control thinking to every dataset I help build.…I’m a video annotation specialist and AI data annotator based in Benin City, Nigeria, with hands-on experience reviewing first-person/egocentric video, doing frame-level labeling, and maintaining high-quality ground-truth datasets.
