    I am looking to supplement my startup bootstrapping with part-time contracting gigs. I have a lot of experience with a broad spectrum of technologies and learn new languages quickly. My area of expertise is objective-c development and the Cocoa APIs. I have a bachelors of science in: Electrical Engineering, Computer Engineering, & Computer Science. Previous employers include: Intel, Oracle, Apple, and a number of side projects. In that time I have done extensive: native iOS and Mac development, server-side REST API development (python), Java, Perl. I dabbled in: SQL, Ruby, HTML/CSS/JS, VHDL/Verilog. I love working on Macs, but am extremely comfortable in most Linux/Unix environments as well. (Scripting and maintenance comes as a second nature.) I'm comfortable navigating 800 page specification documents and am a great team player. Currently I am the CTO of stayinyourprime.com which entails defining our technical architecture and much of the development effort (100% of our iPhone app and a handful of server work). Check out the app here https://itunes.apple.com/us/app/prime/id699009998 for the best example of my work.
