I'm working at a Fintech startup Smartround Inc as CTO in Tokyo(Japan).
In my work, I write Kotlin(server-side), Scala, Vue.js, Typescript, Terraform(aws) and so on.
I especially love Kotlin and Vue.js. I feel these are very simple and sophisticated.

Aside from work, I also work as an OSS developer.

  • Contributor of Kotlin major frameworks (ex. ktor, Exposed, kotlintest) and some small javascript libraries.
  • Creator of kotlin-csv (Pure Kotlin CSV Reader/Writer)
  • Founder and translator of ktor document into Japanese. Project URL

As you can imagine, startup's work is very hard and needs many time. Although I think it is also important as a developer to contribute to the community through OSS activities so I want to do it at the same time.
I want not only to make startup product success, but also to create cool library (Kotlin, Vue.js), and to spread server-side Kotlin into Japanese society.

The salaries of startups are not high, so I want sponsors to keep my standard of living and keep me motivated to developing.
