Freelancer Overview

Over the past few years, I have built hands-on experience in AI training and data labeling through contract and freelance roles with TELUS International AI Data Solutions. In these roles, I annotated text, image, and audio datasets in line with detailed project guidelines, performing tasks such as sentiment labeling, intent classification, entity tagging, relevance scoring, and transcription review. I also applied annotation schemas for content evaluation and language data preparation, consistently delivering high-accuracy work across multiple concurrent tasks while maintaining data security and confidentiality standards. Beyond dedicated annotation roles, I have reinforced this experience through my work as a Field Engineer, where I collected, validated, and organized structured and unstructured engineering datasets, performed quality assurance checks on project records, and ensured data consistency across reports. I also completed foundational certifications in Data Analytics and Artificial Intelligence, which deepened my understanding of how clean, well-labeled data supports machine learning workflows. Altogether, my background spans the full annotation cycle; from following guideline compliance and flagging inconsistencies to final quality validation; making me a reliable contributor to AI data projects.

Labeling Experience

Yes, I do have data labeling and AI training experience

Yes, I do have data labeling and AI training experience. I have worked as a Freelance Data Annotation Specialist with TELUS International AI Data Solutions, where I annotated text, image, and audio datasets, performed sentiment labeling, entity tagging, intent classification, and content evaluation, and conducted quality assurance checks to ensure annotation accuracy. Prior to that, I served as a Junior Language Data Annotator at WordBridge Agency for over two years, where I annotated domain-specific text data, validated labeled datasets, and applied annotation frameworks for entity recognition and relevance assessment. I have also worked in a Translator and Localization Specialist role with TELUS, where I evaluated structured and unstructured text data specifically for AI training purposes. In total, I have several years of direct data labeling and AI training support experience across multiple platforms and task types, including text classification, pairwise comparison, transcription review, and dataset validation. I also hold certifications in Data Analytics Fundamentals and Introduction to Artificial Intelligence. I would appreciate being marked as having prior data labeling experience, as it accurately reflects my background and the value I can bring to this role.
