[update 02-2012]: Since 2010, I've been working with G o o g l e corp engineering to create front end prototypes, make UI/UX recommendations and run usability studies for one of their beta applications; I can point to examples when the status is public.

I worked with the PayPal Web Development engineering and graphics teams to create application prototypes and improvements to the PayPal web site user experience. Also responsible for implementing xhtml, css, and YUI scripting code to help integrate the new 3rd party PayPal Apps.

UI design and development: I was asked to create a simple, clean design that also featured flash demos, lots of product photo work, and an effective 'walk-through' style that quickly gave customers a clear view of the King-Tek EDM process and facilities. The site is 508 compliant with a css layout in which the javascript degrades gracefully for non-css and jscript users.

Cool project: Gmail and other web-mail clients strip out images and external css, so for Voltage SecureMail I created background vectors and shadows using only cross-browser compatible inline CSS. (The company logo, if not included deprecates to the ALT text):

Web development and graphic design: Day to day webmaster duties included updating the entire Ketera site, news and press releases, etc.
Notable accomplishment: In response to a spam-bot attack on their contact forms which had Ketera blacklisted by Google and other search engines, I developed hack-resistant php and salesforce-integrated registration forms with domain checking and rigorous fields validation, and got them off the black list :o)
I also created original graphics, logos, and flash for the Ketera site, plus marketing print collateral, data sheets, white papers, etc.
