Throw me your gnarliest code, I can make it shine

I'm a Software Craftsman with 20+ years of experience building from web applications, to ETL, BI, data mining solutions and even some desktop applications.

I prefer to work on the web but away from the browser. I enjoy refactoring and optimization workloads and I love to explore new technologies.
I have a clear preference towards Ruby but I can work in any technology - throw me some Javascript, Java, C#, Clojure and I'll pull on all my experience to do an outstanding job.
