Freelancer Overview

I am a detail-oriented Data Annotator with over 4 years of hands-on experience in data labeling, cleaning, validation, and quality assurance for large-scale projects, including donor-funded initiatives in health and community development. My background spans annotating text, image, audio, and video data using platforms such as Appen, Clickworker, Toloka, and tools like Labelbox, Roboflow, and CVAT. I am skilled in following strict annotation guidelines, ensuring data accuracy, and collaborating with teams to improve AI model training datasets. I am highly adaptable, quick to learn new annotation tools, and comfortable working with both structured and unstructured data. My commitment to quality and strong time management allow me to consistently deliver reliable results for AI and machine learning projects.
