Muhammad Hasnain R.
AI Data Annotation Lead | CVAT, Semantic Segmentation, Medical Imaging
I help AI teams build cleaner training data for computer vision, medical imaging, autonomous systems, and other high-stakes ML applications. My focus is production-ready data annotation that improves model performance and reduces costly errors at deployment. I specialize in semantic segmentation, instance segmentation, object detection, video annotation, and 3D LiDAR labeling. I work with CVAT, Labelbox, Roboflow, SuperAnnotate, and Label Studio to deliver structured datasets in formats like YOLO, COCO JSON, Pascal VOC, XML, and CSV. I also have hands-on experience with DICOM, MRI, CT, X-ray, and other medical imaging workflows, along with automotive and AgTech annotation projects. My process is built around precision and quality control. I apply detailed annotation standards, review edge cases carefully, and use inter-annotator consistency checks to help ensure reliable results for your model training pipeline. Whether you need a pilot batch, a growing dataset, or large-scale annotation support, I can help you move faster with cleaner data. If you need a dependable annotation partner for computer vision or medical AI, send me a message and let’s discuss your project.
