Here is one of achievements (shortened):

The developer. In the 2012, I led a project called Tixis. I was the only one developer (me later added two more, but at that time I was alone). The project has been made with the Ruby on Rails and it was one of classified-sites. Just a list of events with date/times, news, etc, simple show bill site. At one point the customer has made the pivot and made the decision to transorm this system into a full eTickets service. I had to plan and develop a system of buying tickets for the event. And I did it, I also successfully applied Backbone.js the first time.
