Freelancer Overview

I am a dedicated Remote Data Annotation Specialist with over 3 years of experience supporting AI and machine learning projects. My expertise spans labeling and annotating images, text, audio, and video with a high degree of precision, including tasks like bounding boxes, segmentation, object detection, sentiment analysis, and text classification for NLP models. I have successfully trained and quality-checked large datasets, consistently achieving a QA review accuracy rate of 97-99%. I am skilled in using tools such as Labelbox, CVAT, SuperAnnotate, Doccano, Scale AI, and various crowd platforms, and I am comfortable working independently or as part of remote, international teams. My background in IT, combined with strong attention to detail and the ability to meet tight deadlines, allows me to deliver high-quality annotated data essential for AI development.
