I do the whole web development stack, in just about every language out there. I've used various Java technologies (EJB3, JSF, Icefaces) and lately have been doing rich clients via ExtJS (raw javascript) and GWT/GXT. I've also dabbled with Python, including Django and sqlalchemy. When first learning Python I built my own python web framework as an exercise. I know C/C++ but it's been awhile since I got my hands dirty.
