Freelancer Overview

Detail-oriented Data Labelling and AI Training Specialist with a Computer Science background and hands-on experience annotating, validating, and organizing structured and unstructured datasets for supervised learning tasks. Experienced in text classification, intent labelling, data quality assurance, and guideline-based annotation. Proven ability to maintain consistency, accuracy, and high attention to detail across large datasets in remote, task-driven environments.

Labeling Experience

Text Classification & Intent Labeling Project Experience

ClickworkerTextClassificationText Generation

I performed intent annotation and text classification by categorizing user-generated text into predefined categories such as request, complaint, inquiry, and feedback. I ensured guidelines were consistently applied, reviewed labeled datasets for errors, and standardized naming conventions. Additionally, I contributed to decision documentation for complex or ambiguous cases. • Corrected mislabeled or inconsistent text entries • Supported rule-based categorization and case documentation • Focused on maintaining annotation quality and uniformity • Applied structured decision criteria during classification tasks
