I take in consideration when building sites the SEO, using multiple techniques to push the main point of the website and raise the sites rankings on search engines.
I have also done some Cocoa Touch using Objective C to build iOS Apps. One of which is on the App Store. I developed these with the Xcode program by Apple.
Wordpress is another field I am working in, which I use many themes and not just used the generic code/style, but also adapted it for the customers needs. This is where I have read and adapted with PHP the most.
