What I'm looking for

I'm seeking remote or hybrid data annotation roles where I can ensure high-quality labeled data, improve annotation workflows, collaborate with cross-functional teams, and grow into broader ML data responsibilities.

I am a dedicated data annotator with experience delivering high-quality labeled datasets for AI and machine learning projects. I have worked on image, video, and text annotation using tools like CVAT and collaborative platforms.

At CloudFactory and on CVAT projects, I maintained annotation consistency and met strict deadlines. I applied bounding boxes, segmentation, and classification techniques to improve model training data.

I prioritize accuracy, quality assurance, and clear communication with project managers and cross-functional teams. I am seeking opportunities to optimize annotation workflows and contribute to reliable ML datasets.
