Freelancer Overview

With a strong background in data analysis, mathematical modeling, and big data research from my graduate studies at Kyoto University, I have hands-on experience working with R language for data analysis and forecasting projects, such as airport passenger flow and utilization prediction. Throughout my career in digital marketing and e-commerce, I have managed and analyzed large datasets to optimize business strategies, client acquisition, and customer satisfaction. My attention to detail, experience with data-driven decision-making, and ability to structure and process information make me well-suited for data labeling, annotation, and AI training data roles. I am eager to apply my analytical skills and technical knowledge to support the development of accurate and high-quality AI systems.
