What I know
I am well versed in many different web technologies, covering both Client & Server Side development. These include, but aren't limited to:
Outside of web specific knowledge, I am, if i do say so myself, not too shabby with Adobe Products, such as:
Photoshop Illustrator Fireworks Flash AIR
I use both SVN and Git for development repositories, and have used various others including Mercurial and CVS.
Although I lean towards Windows, I am very familiar with Ubuntu, OSX, Fedora, FreeBSD and various other operating system flavors.
To Scratch or Not To Scratch...
I can fully build a website from scratch, including server setup via SSH, Database implementation, Designing the site and building it.
That said, not everybody wants a site built from the ground up, thus I have also used various Content Management Systems / Hosting Services such as Squarespace, Wordpress, Blogger, and Tumblr, and have even built my own from time to time.
