David Davis’s Summary

Software Developer, and Project Manager experienced in a wide variety of web technologies. Particularly interested in client/server applications, ajax and comet.

When I was at Six Apart, I created a JavaScript and CSS concatenation plugin for Perlbal. Large lists of JS and CSS source files could be loaded with a single URL, significantly speeding up page load times. The last-modified header is also supported to avoid resending data. It is still used on all of Six Apart's products, Vox.com, MovableType, Typepad, and their former product Livejournal.com (Look for the long comma separated script and link tags in the sources)

I've built the following servers (in Perl) from scratch and for fun: FTP, SMTP, IMAP, HTTP, HTTP/DAV, IRC, SOCKS5

I have also built a web desktop at cometdesktop.com that includes live demos of my work with cross domain comet and pseudo-sockets with data framing. The IRC and Jabber clients process raw protocol data proxied through a custom built scalable HTTP server and socket proxy (sprocket.socket). The web server is built on top of my very own networking framework in Perl, which is available online and is open source. (Linked from my website, xantus.org)

David Davis’s Specialties:

Started the Cometd project with Alex Russell of Dojo, and Greg Wilkins of Webtide (Jetty), First to create a browser based pseudo-socket library.
