I've created and/or maintain a number of Ruby Gems (Grocer, GitTracker, DumbDelegator, pg_search, minimagick) and share a lot of side-project code on GitHub. I've been building the web since the early 2000's and first started using Ruby in 2007. I've helped a number of teams move from SVN/CVS/TFS to Git. I enjoy helping people along the road from "Testing to Test-First to Test-Driven" (http://stevenharman.net/from-testing-to-test-first-to-test-driven).
