What I'm looking for

I seek a role on a collaborative data team where I can apply precise annotation and QA skills, contribute process improvements, and support ML model quality while working remotely or on-site.

I am a meticulous data annotation specialist with over three years' experience labeling and validating image, video, and text datasets to support machine learning and AI model development. I consistently meet and exceed targets while maintaining rigorous data quality standards, contributing to improved model perception and reliability.

I have hands-on experience with bounding boxes, polygon annotation, semantic segmentation, NER, and advanced Excel, and I collaborate proactively with QA and team leads to reduce annotation errors and streamline processes. I am adaptable to remote, hybrid, or on-site roles and ready to start immediately to bring precision and efficiency to a forward-thinking data team.
