Profile
I'm a software engineer based in Tokyo with 5+ years of experience in the software industry. My focus area for the first few years in my experience was web applications, although I've been keeping a full-stack perspective by working on DevOps with embedded engineering team. I like open-minded and scientific discussions, and I really love to develop software & collaborate with teammates.

Development leader
Oct 2022 - Mar 2023
- I took leadership of the development team for the new IoT service project, which is already behind schedule.
- There are few engineers who have enough experiences, so I have to lead the team with a full-stack perspective.
- By adopting servant leadership style, we organized non-development factors that had become bottlenecks and led the team to a quantitative goal with DevOps in mind.
