What I'm looking for

I seek a collaborative role in data annotation or QA where I can apply CVAT and annotation tools, ensure high-quality labeled datasets, and grow within ML data operations.

I am a detail-oriented data annotator with hands-on experience labeling images and video for object detection, classification, and segmentation using CVAT and commercial tools like Haisty AI and Relo Metrics. I consistently meet daily productivity and accuracy targets, perform quality assurance, and streamline workflows through careful dataset organization and collaboration with QA teams.

I hold a Bachelor of Technology in Computer and Information Sciences and apply strong task and time management, client-relations, and communication skills to deliver reliable labeled datasets under tight deadlines. I seek to contribute to teams that value high data quality, clear guidelines, and continuous process improvement.
