Labeling Experience

Freelance AI Data Specialist & Transcriptionist

CVATImageClassification

I annotated and labeled over 8,000 data points across text, image, and audio formats for multiple AI model training projects, ensuring data relevance and high accuracy. My work improved model performance for numerous international clients by strictly following labeling protocols. Throughout this period, I managed and validated the quality of datasets to deliver immediate, production-ready files. • Maintained 99% accuracy in all labeling tasks. • Utilized tools such as CVAT and Label Studio for annotation work. • Worked on image, text, and audio data for diverse AI domains. • Delivered finalized datasets systematically ahead of deadlines.

Structured Data Recording Initiative

TextClassification

I recorded, organized, and initially annotated more than 2,500 structured textual records from public digital sources as part of a self-directed initiative. The process incorporated systematic recording and full quality checks to generate production-ready training files. All data outputs supported the development of AI models by providing clean, structured benchmarks. • Ensured thorough data validation before project completion. • Self-directed work with independent quality assurance cycles. • Outputs tailored for AI training file standards. • Addressed a range of public data sources for dataset diversity.
