To start off, I would like to say a few things about me personally.
I live in a Richmond, VA suburb. I have been working with computers for several years now and I am now certified.
I develop websites with PHP as the backend, XHTML as the frontend, and CSS for design. I use JavaScript and JSON to add some flair to the site. For example, the 'Recent Tweets' functionality of my site is 100% custom JavaScript based off of jQuery that uses a JSON query to get my five most recent tweets and displays them on my site at a 5 minute interval.
I use web standards when coding, though there are some exceptions. Pending CSS3, I have had to use non-standard, but standards compliant proprietary methods of rendering rounded borders in CSS. I use the -moz and -webkit proprietary methods of displaying the rounded borders to anyone who uses Mozilla or Webkit's rendering engines. Examples include Firefox (Mozilla), Safari (Webkit), and Google Chrome (Webkit).
