About

I'm a software engineer and M.S. student at The University of Osaka. I like taking a vague problem, breaking it into parts I can measure, and shipping something that works — whether that is a research system, a backend service, or an app on Google Play.

Background

I studied physical education at National Taiwan University of Sport and then worked as a youth football coach and referee.

Watching AlphaGo and early GPT-3 demos convinced me that software and AI would shape the decades ahead, so I changed fields. I moved to Japan in 2020, studied at a Japanese language school, and entered the School of Engineering Science at The University of Osaka in 2022.

Getting in took more than effort. After a first year without clear progress, I sat real entrance exams to see the gap, rebuilt my study plan subject by subject, and focused on my weak areas. That habit — measure first, then change the method — still shapes how I work.

Today I'm a graduate student in the Yamaguchi Lab (mobile computing and urban digital twins), researching fast simulation of light pollution from Urban Air Mobility. Outside research I build and publish Android apps under the Forger Wise name.

What I want to do

I want to work as a software engineer with backend systems at the core — APIs, data, and cloud infrastructure — and connect AI/ML to features that users can actually feel.

Next, I want to learn how large systems are run in production — quality and operations, design decisions made as a team, and understanding what users and customers really need. I'm based in Osaka and plan to build my career in Japan.
