AI Data Annotator skilled in labeling text, images, audio, and video with strong attention to detail to improve machine learning models.
NigeriaWhat I'm looking for
I’m an AI Data Specialist focused on supporting the development and evaluation of AI-generated content through structured data collection, annotation, and quality review. I’m known for strict guideline adherence and consistent delivery of accurate, high-quality labeled data for multilingual and low-resource language AI systems.
In my current role as a Senior AI Data Annotator, I execute large-scale data collection, evaluation, and annotation on Hausa and English datasets. I conduct pairwise comparisons and ranked response evaluations using defined rubrics, complete counting and classification tasks, and tag objects across text, image, audio, and video while reviewing model outputs for relevance, coherence, and safety.
Previously, I served as an AI Data Quality Reviewer and a Machine Learning Data Contributor, where I performed linguistic quality checks, categorized and labeled large training datasets, flagged inaccurate outputs, and supported dataset validation and inter-annotator consistency checks. With a Computer Science background and training in AI data ethics and quality assurance, I bring a disciplined remote-work approach that prioritizes quality, bias awareness, and reliable outcomes.
