Cloudfactory Annotator

CloudfactoryImageBounding Box

As a Cloudfactory Annotator, I worked on complex image and video datasets to train computer vision models through precise bounding box, polygon, and keypoint annotation. Frame-by-frame analysis ensured consistency in object tracking and classification across changing conditions. I maintained strict quality assurance standards to deliver high-accuracy, client-compliant datasets for machine learning. • Rapidly adapted to new project taxonomies and evolving guidelines. • Resolved edge-case ambiguities by providing feedback to project leads. • Achieved high precision in localized labeling tasks for AI development. • Mastered multiple proprietary annotation platforms for improved throughput.
