    Experienced web developer of SaaS systems

    United States - Last active: 09/27/2013 - Tests: 1 - Portfolio: 8

    I have over 15 years of software development experience on all types and sizes of projects for customers in the education, pharmaceutical, non-profit, defense, and commercial markets. My expertise is in web-based SaaS systems. Until 2010 I led a team of about 30 developers on a Microsoft ASP.NET SaaS system for the college/university space. Since early 2013 I worked writing automated QA integration tests for a Ruby on Rails app using Rspec and Capybara. (From 2010 to 2012 I took a break from software to attend music school. I'm currently a musician, and I support myself by doing software development.) I am currently looking to do more Rails automated QA testing, Rails development, or manual QA. I'm always open to other projects that meet my skill set, though.
