@mercymacharia
AI data annotator focused on text and image labeling, with training in evaluating AI-generated responses.
What I'm looking for
My self-directed AI Data Annotation Training introduced me to text classification, sentiment analysis, intent identification, and named entity recognition. I also studied image annotation methods, including bounding boxes, polygons, segmentation, and keypoints.
Through this training, I learned to follow annotation guidelines, check labeling consistency, handle unclear cases, and evaluate AI-generated responses against specified criteria.
At Kenya Marine and Fisheries Research Institute, I supported laboratory and research activities, assisted with sample handling and recording results, and maintained documentation. At Zain Pharmaceutical, I supported quality assurance and quality control activities, including laboratory documentation, sample handling, and routine quality checks.
