I have 42 years of experience programming, on systems from the smallest to the largest. Since 2008 I've specialized in Ruby on Rails, with a side of iOS/OSX and whatever else is needed to get the job done - recent work also includes Elixir, VueJS, Sinatra, AngularJS,CoffeeScript, node.js, Arduino, Swift, and the Pebble SDK.
I treat my code as an expression of art and beauty, and often say:
software is to poetry as
architecture is to sculpture
In addition, I have a well-rounded interdisciplinary background with over 15 patents and three degrees - Computer Science, Art and Dance. Whatever your specific domain, I'm sure to catch on quickly and implement your vision with passion and enthusiasm.
Bring my agile and responsive development style to your project. I communicate well, will make sure you're comfortable with every aspect of the development process, and will not sell you anything you don't need.
I strive always to underpromise and overdeliver, ahead of deadline and under budgetemail me
