Freelancer Overview

I am a detail-oriented data annotator and data quality specialist with over 7 years of experience in data labeling, verification, and quality assurance across education, research, and compliance domains. My expertise includes annotating image, video, and structured datasets using tools like CVAT and working with formats such as JSON and CSV. I excel in applying computer vision concepts such as bounding boxes, classification, and tagging, while ensuring strict adherence to guidelines and high standards of accuracy. I have a proven ability to review, clean, and validate large datasets, design quality-check workflows, and collaborate remotely with cross-functional teams. My background in AI training data, data analytics, and technical training allows me to consistently deliver reliable, high-quality annotated data for machine learning and research projects.
