I am a Ruby on Rails developer with extensive knowledge of Ruby on Rails, SVN, JavaScript (plus Scriptaculous and Prototype) and MySQL. I have developed high volume sites from design to the production stages that use MemCache as well as many other custom performance/scalability modifications. Given my work experience, I bill at $100/hour at 15 minute increments (i.e. $25 per 15 minutes). Can provide references upon request.
