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 in Computer Science and Mathematics 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 worked as a freelance JavaScript engineer from 2015 to 2020. My main partners were CureApp, Recruit, and SEQSENSE.

I've been working full-time at Deno since January 2021. I work on Deno CLI, Deno Deploy, Deno Standard Modules, and other various related projects.

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 the main OSS projects I've been contributing to.
