Creator of Portly and author of several OSS projects.
I have the chops to code a solid site in Sinatra, or I can create extremely complex sites in Ruby on Rails (or even plain Rack) and perform all the server setup for a dedicated server. We're talking background processes, scheduled activities, email relaying, whatever you need. Use me for consulting or development.
Rails, Rack, Redis, RSpec, PostgreSQL & Mongo. Backbone, HAML, SASS, CoffeeScript. iOS!
You name it, I know it or will know it. (Just give me a couple days)
