Ruby on Rails
Love ROR as flexible and powerful freamework. Easy to prototype and move to production from them. Backend & frontend we build using stable & production ready gem's.
PostgreSQL, MariaDB, MongoDB, Redis - for production databases. Gem's: Devise/CanCan, Haml/Slim, Compass, Paperclip/Carrierwave, Sidekiq/DelayedJob, ActiveAdmin/Rails_admin and Capistrano & Docker - for deployment process. Our apps work on high perfomance setup servers in: servers.com or digitalocean.com or aws.amazon.com with top's production-ready ruby gems and tools.
