Labeling Experience

Image Annotation / Data Labeling (Freelance / Practice Work)

OtherImageClassification
This role involved reviewing and correcting annotated images for both accuracy and consistency. I identified missing or incorrect labels in auto-generated image datasets. I ensured all work adhered strictly to project-specific annotation guidelines and maintained quality standards across repetitive annotation tasks. • Reviewed images and ensured label accuracy • Corrected annotation errors in structured datasets • Followed project guidelines and instructions • Maintained high attention to detail throughout the tasks
