We got into python web development back in 2004 with CherryPy, Cheetah Templates and later some Paste. Since then we've been experts in Pylons, Turbogears, and a few handrolled frameworks. But our favorite thus far has been Django.
Before 2004 our team worked in PHP, .NET and Java. We can still work with these today, but we much prefer the speed and power of Python.
On the front end, we've done consulting with Adobe Consulting, so you can rest assured we're among the best in the business at Flash and Flex. We also consider ourselves among the best with YUI, JQuery, good ol' CSS and HTML4.0/XHTML/AJAX. We can do GWT and Pyjamas too…
