Background
I’m a Software Engineer based in Tokyo, Japan, currently working at Fast Retailing. With nearly a decade in the tech industry, I’ve worked with leading technology companies across Southeast Asia and Japan.
What I do
I’m deeply passionate about backend engineering — building robust, scalable systems that power modern applications. I also have extensive experience in data engineering and cloud infrastructure, particularly with GCP and AWS.
There's something incredibly satisfying about architecting systems that can handle millions of requests while remaining resilient and maintainable.
