Freelancer Overview

I am an experienced data annotator with a background in telecommunications engineering and hands-on expertise in AI training data projects. Currently, I work remotely for RWS Group, where I perform a variety of annotation tasks on platforms like Parimango and Multimango, including pairwise comparisons, object tagging, character-consistency checks, and verifying audio transcript accuracy to enhance speech recognition systems. My technical training, strong problem-solving abilities, and familiarity with both computer vision and audio data labeling enable me to deliver high-quality, consistent results. I am skilled at adapting to new tools and workflows, collaborating effectively in team environments, and ensuring data quality for machine learning applications.
