I label high-quality AI training data with clinical-grade precision and rigorous protocol adherence.
NigeriaWhat I'm looking for
I'm completing DataLensAfrica's Essentials of Data Labeling and Annotation course, where I've labeled retail shelf, aerial imagery, and autonomous-driving datasets in Label Studio using bounding boxes and category tags.
I export labeled datasets in COCO JSON format, troubleshoot annotation tool issues independently, and work toward 95% labeling accuracy for onboarding readiness.
As a final-year Medical Laboratory Science student with clinical postings at University of Nigeria Teaching Hospital and Godfrey Okoye University Teaching Hospital, I bring disciplined documentation, quality control, precise measurement, and careful adherence to multi-step protocols to AI training data and quality-review work.
