Employment
Experience
- CMS for R7.com (Development)http://r7.com
R7.com is the second Web Portal from Brazil and they had a poor CMS written in Java.
My team worked to build a new solution to replace it, using Ruby, Event Machine, RabbitMQ, Varnish, and various other tools. Today the project is still growing, so that proves our effort in building a quality system was worth it.
