Freelancer Overview

I am an experienced IT professional with a strong background in data annotation, data labeling, and AI training data tasks, gained through hands-on work with platforms like Appen, Mturk, Clickworker, Outlier AI, and RWS AI. My projects have included image analysis, video annotation, audio transcription, and data entry for AI model training across domains such as computer vision and natural language processing. I am highly skilled in managing and securing large datasets, performing quality checks, and ensuring data accuracy for machine learning applications. My technical expertise is complemented by experience in database management, web development, and cloud services, allowing me to efficiently handle end-to-end data workflows for AI and analytics projects. I am detail-oriented, adaptable, and committed to delivering high-quality, reliable training data for AI solutions.
