I am a professional web developer. I have worked on many projects. Mostly - big projects. Including state-level projects and one commercial project for a company with millions of dollars of investments.
Personally, I have created several APIs with Ruby on Rails with REST MVC architecture. I have experience with high interactive apps with Redux (and, older, Flux) architecture and React library. Familiar with WebSockets and RethinkDB (and certainly with less "trendy" PostgreSQL, MongoDB and MySQL, too). I write unit tests for my code. Performance tests are also familiar to me.
I have been through the whole development cycle many times including the part of a remote server's deploy setting. Command line one love <3 Git the best. Ssh rocks!
