About
Hi, I'm Koki Kazaore. I'm originally from Shiga and now live in Tokyo, Japan.
I work as a software engineer at a logistics SaaS company. My core is backend development with Ruby on Rails, but I work across the full stack, from React on the frontend to the AWS infrastructure behind it.
Before that, I studied IoT and network security at the Graduate School of Engineering, Fukui University.
My hobbies include working out and watching sports. I like various kinds of sports, but I'm especially fond of soccer, baseball, and American football.
I'm grateful to spend my days building things I care about.
