Rails, Postgres, Passenger/Nginx, Redis, Java, Memcached

JQuery, Haml, Sass, Bootstrap, Compass

Started with EC2, now on Linode.

Yet to be announced food ordering app:

Rails (purely as API), PostgreSQL

AngularJS, Bootstrap, Scss, Compass, Yeoman

Nginx as static assets server (serving everything frontend related) and as reverse proxy for the backend. Probably Passenger or Puma for the application server.

Planning to try DigitalOcean.
