I'm a web and iOS developer in Chicago. For the last three years, I've been doing full-time freelance and contract work under the moniker Atomic Promise.
I hand-crafted my own blog software in Ruby on Rails. This allows me full control over everything without dealing with a ton of extra cruft. As it evolves, I'm planning on open-source-ing it on my GitHub. If you're interested in seeing the source before then, just drop me a line.
