Hello. I'm Yoshiya Hinosawa.


I'm a software engineer in 🇯🇵. My main programming language is JavaScript. I've published a number of npm modules. I write programs in other languages as well, like python, ruby, groovy, java, bash etc. I published some ruby gems, maven packages, gradle plugins.

I majored Computer Science 🖥 in Kyoto University and graduated in 2009 with a BA degree.

I worked as a full stack engineer in GREE (A Japanese social gaming company) from 2012 to 2014.

I've been working as a freelance JavaScript engineer since 2015. My main partners are CureApp, Recruit Technologies and Recruit Lifestyle.

I often use the id `kt3k` in several places. `kt3k` is derived from kata-tataki, a Japanese word for `shoulder massage` 💆. I chose this name for the account name of a certain small online game many years ago. I didn't intended to use this name for such long time, but the friends there kept calling me by that name for long time, and it gradually became my favorite id.

OSS Projects

These are my main OSS projects (in 2018).
