Freelancer Overview

An expert in AI and computer vision, I specialize in high-quality data labeling and annotation for machine learning training datasets. I have hands-on experience with image and video annotation, bounding boxes, segmentation, and classification tasks, ensuring data accuracy and consistency for AI model development. My work has supported projects across object detection, facial recognition, autonomous systems, and more, contributing to improved model performance and reliability. Proficient in tools such as Labelbox, CVAT, and Supervisely, I combine technical expertise with strong attention to detail to deliver scalable and precise datasets. I am adept at following complex labeling guidelines, maintaining quality control, and collaborating with AI teams to meet tight project deadlines. My commitment to data excellence and understanding of computer vision principles set me apart in AI training data preparation.

This project involved preparing high-quality training data for computer vision models used in object detection and image classification. The scope included annotating thousands of images and video frames with bounding boxes, segmentation masks, and classification labels according to detailed project guidelines. I performed tasks such as identifying and labeling objects of interest, ensuring consistency across similar images, and verifying annotations for accuracy. The project size included over 50,000 images, and I collaborated closely with the AI development team to meet strict quality standards. Quality measures included cross-checking labels, following annotation protocols, and using validation tools to ensure datasets met the required precision for optimal model training.
