Freelancer Overview

I have hands-on experience working on data labeling and AI training projects through platforms such as Outlier and TELUS International. In these roles, I worked on tasks that required carefully reviewing, labeling, and evaluating data according to detailed guidelines to help improve AI models. This included assessing accuracy, relevance, and quality while maintaining consistency and attention to detail. Through this work, I developed strong skills in following complex instructions, critical thinking, and providing clear, structured feedback. I am comfortable working with large volumes of data, meeting quality standards, and managing tasks independently in a remote environment. My experience with AI training data has strengthened my ability to work accurately, adapt quickly to new project requirements, and contribute reliably to improving machine learning systems.
