AI Training Data Annotation – NLP & Computer Vision Projects
Worked on multiple AI training data projects involving both NLP and computer vision tasks. Annotated and validated over 20,000+ data points including short-form text, search queries, product reviews, and real-world images. For NLP projects, I performed sentiment analysis, intent classification, and Named Entity Recognition (NER), ensuring precise span tagging and strict adherence to annotation guidelines. Maintained over 95% quality accuracy scores based on internal audits and reviewer feedback. For computer vision projects, I conducted object detection and bounding box annotations for datasets involving vehicles, pedestrians, and retail products using CVAT and similar platforms. Carefully handled edge cases such as occlusions, low-light images, and overlapping objects to improve model training performance. Additionally, I participated in quality assurance (QA) reviews, resolving annotation inconsistencies and improving inter-annotator agreement.
