Summary

After graduating from the University of Tsukuba (College of Information Science) in 2002, I joined a Tokyo-based system integrator (~100 employees at the time). I started in Windows infrastructure, working on system design, deployment, and operations for organizations ranging from small teams to enterprises with tens of thousands of users. From 2007, I led technical support and training for internal engineers while directly intervening in technically challenging projects.

I then moved into business development — serving as Deputy General Manager and General Manager in the Marketing and Business Planning divisions. Throughout, I continued to develop technology-driven services and delivered numerous talks at events and seminars. I’ve authored a published book and contributed articles to multiple magazines and web publications. I’ve been a Microsoft MVP award recipient continuously since April 2014.

In 2018, I pivoted back to a pure technical role as a Senior Expert, focusing on community leadership (HCCJP — Hybrid Cloud Community Japan), YouTube-based technical evangelism (~11,000 subscribers), and internal cloud platform operations and automation. After roles in the CCoE (Cloud Center of Excellence) and R&D office, I drove cloud technology standardization and solution development.

Since October 2025, I’ve been a Senior Specialist in the newly established AI Transformation Division, leading the planning, design, and implementation of business transformation solutions powered by AI agents (Agentic AI).

My core strengths are deep expertise in Microsoft technologies — from on-premises to cloud to generative AI — combined with exceptional ability to explain complex concepts clearly. I’m also highly skilled in automation through programming and AI agents.
