What I'm looking for

I seek remote roles contributing to high-quality AI training data—annotating image, audio, text, and video—applying ATD methods, ensuring data quality, and working on sports analytics, facial recognition, or education-tech projects with collaborative teams.

I am a Data Annotation Specialist with over five years of experience labeling image, text, audio, and video datasets for AI and machine learning projects.

I have delivered Autonomous Training Data and high-quality annotated datasets using CVAT, Clickworker, Appen, and CloudFactory, applying bounding boxes, polygons, and semantic segmentation. My work supported sports analytics, facial recognition, and education technology projects where accuracy and consistency were essential.

I focus on quality assurance, data validation, and efficient remote collaboration, consistently meeting accuracy targets on both microtasks and complex annotation assignments.
