Freelancer Overview

I am a detail-oriented AI data annotation specialist with hands-on experience labeling and reviewing over 5,000 images, videos, and text samples for machine learning training. My background includes working on projects involving image and video annotation, sentiment analysis, entity tagging, and dataset cleaning, where I consistently achieved high accuracy and audit approval rates. I am skilled in using annotation platforms such as Labelbox, Super Annotator, Scale AI, and Hive Data, and I have a strong grasp of quality control, error tracking, and guideline adherence. I thrive in remote, project-based environments, bringing a high level of focus, accuracy, and consistency to every task, and I am committed to supporting the development of robust AI systems through precise data labeling and annotation.
