Spencer Mattison

Kammeko / Ruby on Rails Backend Developer

Full Stack Web Developer

Initially graduating with a Japanese Language degree and then living in Japan teaching English, I decided to try out programming because of my initial interest in computers and have enjoyed every bit of it.


In the future

言語と教師としての力をつかて、プログラミングを教えたいです。 I want to use my language and teaching skills to teach others about programming.
