Software Engineer / Engineering Student

ABOUT ME

I am a second-year master's student living in Tokyo.

Inspired by competitive programming, I became interested in personal development and was gradually drawn to the appeal of software engineering.

In university, I majored in Computer Vision and conducted research on knowledge distillation-based Federated Learning. In graduate school, I am focusing further on FL.

I have gained experience as a student intern at various companies and plan to start my career as a platform engineer next year. In recent years, I have been interested in Platform Engineering and MLOps.

My hobbies are reading technical books and managing the lab's servers.

My goals for 2025 are to have a paper accepted in a journal and to contribute and present a lot in the tech community.
