We (
Red Panthers) are looking for Ruby on Rails developers for a short term contract of 3 months to assist us in a couple of our on going projects. The project uses Rails 4, Angular JS, Postgres and Sidekiq. The project does use a lot more of angular than rails, but we have an in house expert who would take care of that so the contractor need to be only strong in rails. Do 
contact me directly if you are interested and would like to know more details about the opportunity.
