Freelancer Overview

I have experience supporting AI training data projects involving image collection, handwriting recognition, and conversational text refinement. I gathered and labeled large datasets under strict accuracy standards, oversaw quality control for thousands of handwritten texts in multiple languages, and contributed to improving AR and natural language models. My strengths include data accuracy, process management, and meeting tight deadlines, which allow me to deliver consistent, high-quality results for AI refinement. Managed and delivered two large-scale international data collection projects for leading technology clients in the AR and handwriting AI sectors. Acted as the central coordinator between DataPure and distributed contributors, overseeing planning, onboarding, execution, and delivery for each project.
