You will get High-Quality Data Annotation for Accurate AI Model Training
Project details
I help AI and machine learning teams build accurate, reliable models by creating clean, high-quality datasets through expert data annotation and data labelling. I specialize in image labelling, object detection, and image segmentation, delivering precise and consistent labels for images, videos, and text. My work ensures that AI models perform better, save training time, and reduce costly errors. I handle diverse tasks including bounding boxes, polygons, segmentation masks, keypoints, multi-class detection, as well as text tasks like NER, OCR, text classification, and sentiment analysis. Experienced with tools like CVAT, V7 Darwin, Label Studio, Roboflow, Labelbox, Doccano, and LabelImg/LabelMe, I deliver datasets in COCO, YOLO, Pascal VOC, CSV, or custom formats. Detail-oriented, communicative, and reliable, I ensure every project passes strict quality checks so clients receive AI-ready datasets that drive real results.
