I am an Azure Support Engineer based in Tokyo, working with enterprise customers on cloud infrastructure and hybrid environment issues.

Before joining Microsoft, I supported MuleSoft products at Salesforce and worked on API development and integration-product research at NTT DATA.

I am passionate about AI-assisted programming and use Microsoft 365 Copilot and GitHub Copilot extensively in my daily work. My long-term goal is to grow toward an AI Engineer, Solution Architect, or Solution Engineer role.

Outside work, I enjoy meeting people, exchanging ideas about technology, and investing in the U.S. stock market.
