    Over the last 6 years I have: -Developed websites in PHP, Ruby (rails), and Python (Django). -Developed complex Ruby on Rails apps using BDD/TDD and agile practices. The following are some of the technologies I have used in developing RoR apps: - MySQL, PostgreSQL, SQLite3 - Rspec, Cucumber, Jasmine - Redis, Resque - Coffeescript, Backbone.js (w/coffeescript) - Haml, Slim, eco, erb - Javascript templates (JST) - Mechanize, Capybara, Selenium, Webkit Headless driver -Written Java Applications including real-time data processing systems. -Crafted the updated the web-development curriculum for the Washington University in St Louis Computer Science department. Migrated the course to use Amazon EC2 in the earlier days of EC2. I was then head TA for the course for 2 years. -Developed a myriad of custom WordPress plugins -Administered WordPress sites -Worked with various startups I prefer to work using agile methods. Agile facilitates communication between client and contractor, and, in my experience results in a better end-product that actually does what the client needs. Unlike many engineers, I enjoy communicating with clients and value open communication and feedback throughout the development process. I have a formal, engineering based education in Computer Science and know "how all this stuff works" from top to bottom. I am an engineer who loves elegant and extensible solutions that will serve you for years to come. I am particularly interested in building cloud based Ruby on Rails sites and Scala Play based applications, however I am open to other contracts.  less
