I develop custom, rich web applications using Ruby on Rails and Ember.js or React. I've worked for 3 startups in the US and Japan, all using Ruby on Rails, Ember.js, and sometimes other Javascript frameworks such as React, Vue.js, etc. I worked on many large projects that served thousands of users. I run my own internet radio station using a SaaS app that I developed by myself. It's all developed from scratch in Ruby on Rails and Ember.js. I run my own blog where I write about technical topics related to Rails and Ember, and released one ebook that got me a few hundred dollars in revenue. I have made open source contributions to many Ruby on Rails related libraries.
