Here's a current project, SimpleRelevance. I am CTO and lead developer. I do webdev / machine learning / algorithmic backend work as well as managing the tech team.
If you go to the api doc you can see how this stuff works from a developer's perspective.
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.
