What I'm looking for

I seek roles focused on high-quality annotation and workflow automation, collaborating with cross-functional teams in remote-friendly, data-driven environments.

I am a detail-oriented Data Annotation Specialist with over five years of hands-on experience preparing text, image, and video datasets for machine learning. I consistently deliver high-quality labeled data—achieving 99% accuracy—by using tools like Segments.ai, Labelbox, CVAT and SuperAnnotate.

I have supported cross-functional teams across finance, agriculture, and healthcare to refine annotation guidelines, reduce discrepancies, and improve downstream model performance. I also automate and optimize workflows with AI-driven tools, increasing efficiency and reducing manual effort.

My background includes remote and on-site roles where I managed timestamped labeling for robotics, property operations data, and large-scale annotation projects while maintaining strong communication, time management, and process-improvement focus.
