Here's a current project, SimpleRelevance. I am VP of Technology and lead developer. I do webdev / machine learning / algorithmic backend work as well as managing the tech team.
If you go to the products page you can see some fun little demos of things I've made in my 20 percent time.
Here's a page for a new project I'm working on: UpChicago.org. That's me learning how to be a web designer.
Oh, and here's another example of my measly but quickly improving design chops: the ribcage. It's the home page for my house.
This is the initial spike for a jquery plugin that uses twitter and the clients' computers to host, manage, and display comments for the given website (free commenting for small self-run and self-hosted sites): JeasyCom
I also have a bitbucket account with more repositories. I have been building up various API wrappers in Python/Django for things like IContact, Constantcontact, Mailchimp, Magento, XCom, EmailDirect, Shopify, BigCommerce, ExactTarget, etc etc, (mostly for work) and I hope to release them all very soon.
Sometimes I write down difficult fixes for things in a blog which you can find here.
