Freelancer Overview

I have experience supporting AI and machine learning projects through data labeling, annotation, and quality assurance across text, image, and customer interaction datasets. My work has involved reviewing and organizing large volumes of training data, identifying inconsistencies and maintaining annotation accuracy. I am proficient in using digital collaboration and productivity tools such as Jira, Airtable, Google Workspace, and spreadsheet tools to manage workflows and track progress efficiently. What sets me apart is my combination of analytical thinking, organization, and project coordination skills.
