This is my work from the the Software Craftsmanship Guild (now called The Software Guild). The most interesting code to look at is in the Labs, since those are fully developed projects versus assignments or short problems.
There are also several projects which got continually refactored, from console application to basic web app, to MVC app, to database CRUD web app. The quickest way to see those projects is to go to Portfolio
Happy to answer questions about any of these projects!
