    Jamie Gaskins

    Ruby/Rails Developer, fluent in HTML5 and CSS3, Agile and TDD zealot

    Australia - Tests: 10 - Portfolio: 8

    My goal is to solve problems with code that I write. I am a competent and experienced developer, having employed both Ruby and C++ in projects that have, to date, generated 8 figures in revenue. I love to research new technologies and hack on code in my spare time. I am a crusader of the holy light of test-driven development; I test every single line of code that I can in as many ways as I can, both in Ruby and Javascript/CoffeeScript. Deploymentwise, I'm fluent with the Heroku platform (both Cedar and previous stacks) and I'm also able to set up a Linux server for conventional deployment using nginx/Apache along with Unicorn or Passenger as app servers. Relational, document and key/value databases and other technologies are also not a problem. In the end, I enjoy writing Ruby code. The primary reason for Ruby and Rails existing is developer happiness — happy programmers are productive programmers and productive programmers ship code.
