I spent about 12 hours straight yesterday developing a framework of an application in PHP. I wrote it with well documented, sematically correct HTML along with elegant CSS and not a single table. It works beautifully in Firefox, Internet Explorer and Safari. My custom authentication script secures the application against unauthorized access but also makes it impractical to show off my work.
Sometimes it is frustrating to write beautiful code or elegantly designed databases and because the work is proprietary or has company mission critical data I am unable to demonstrate my skills. For a long time I have tried to budget a couple of days at the end of each project to update my resume and create a static presentation of the site but with projects running on top of other projects such luxury of time is not available.
