Profile
My first encounter with programming was at age 10. My first programming language was BASIC, and I have been programming since I was 19. Around 2009, learned about domain-driven design and Scala, worked in a large web company developing a large infrastructure system using Scala and domain-driven design(DDD).
Now I am working as a Tech Lead at Chatwork as a Japanese business chat service, released a DDD, CQRS/Event Sourcing system using Akka, HBase and Kafka in 2016. I continue to work as a server-side architect, focusing on developing services based on a message-driven reactive architecture.
私がプログラミングと出会ったのは10歳のとき。初めてのプログラミング言語はBASICで、19歳からプログラミングを続けています。2009年頃、ドメイン駆動設計とScalaの存在を知り、大手Web企業でScalaとドメイン駆動設計(DDD)を用いた大規模なインフラシステムの開発に従事。
2016年にAkka, HBase, Kafkaを使ったDDD, CQRS, Event Sourcingシステムをリリースし、現在はChatworkでテックリードとして働いています。現在もサーバーサイドアーキテクトとして、メッセージドリブンなリアクティブアーキテクチャーに基づいたサービス開発を中心に活動しています。

I mainly develop tools for Scala/Akka. I've also recently created a small library for Rust.
主にScala/Akka用のツールを開発しています。最近は、Rust用の小さなライブラリも作っています。
