Data Annotation Specialist
As a Data Annotation Specialist, I annotated and labeled large-scale datasets for various AI/ML training tasks, including image classification, text categorization, entity recognition, and sentiment labeling. I ensured high quality and accuracy in the labeled datasets by reviewing and validating annotated data in line with project guidelines. I collaborated remotely with engineers to develop annotation schemas and addressed data ambiguities as needed. • Used platforms such as Labelbox, Scale AI, and proprietary tools to efficiently manage annotation workflows. • Delivered clean datasets that improved downstream model performance metrics by 20%. • Maintained 98%+ accuracy rate in all labeling projects, reducing error rates by 15%. • Focused on image, text, and entity-level annotations for state-of-the-art AI development.
