Formulating problem-solving strategies from scratch.
A hands-on PMO consultant driving client success.
After obtaining a Master of Science degree from Kumamoto University, worked for 5 years at Itochu Techno-Solutions Corporation (CTC), driving over 20 digital transformation projects using process simulation for manufacturing and logistics lines. Completed all projects on time and within budget as a project manager, while overseeing the entire product lifecycle from pre-sales, requirements definition, and development to deployment, maintenance, and technical customer support.
Currently at Future Architect, Inc., engaged in an AI-based evaluation project for English speaking exams. Participated from the highly uncertain ultra-upstream phase of scoring engine development, leading the initial conceptualization, requirements definition, and precise data analysis. By designing workflow structures based on Human-in-the-Loop principles to seamlessly integrate human evaluators into the process, successfully implemented a highly reliable auto-grading system that exceeds human scoring accuracy.
