Keita Arai

CEO, Engineer

My vision is to make people happy by developing systems and services. Especially I want to connect people, I believe it will get the world better.
I have been developing web systems with Ruby on Rails since 2004, iOS apps since 2011, web systems with Phoenix since 2016. I'm good at making backend systems without servers using AWS Lambda, DynamoDB etc.
Personally, I like traveling, riding a motorbike, and cooking. I like to hear people's stories and to share my stories.
