Freelancer Overview

I am a detail-oriented Data Annotation Specialist with hands-on experience labeling and categorizing text, image, video, and audio datasets for AI and machine learning model training. My background includes working remotely on diverse projects for platforms like Atlas AI and Appen, where I consistently delivered high-quality annotations by following task-specific guidelines and collaborating closely with QA teams to ensure data accuracy and integrity. I am skilled in using web-based annotation tools, including SageMaker Ground Truth and custom platforms, and have a strong track record of meeting deadlines while maintaining strict attention to detail. My experience spans computer vision and NLP tasks, and I am adept at handling sensitive data and adapting to new workflows in fast-paced, project-based environments.
