I've written a number of major production web applications and supporting libraries/microservices in Ruby. Collectively they're serving around a billion web requests per month! I've been a regular speaker at a number of Ruby conferences (around two dozen) and a prolific StackOverflow contributor on this topic.

I've written .NET apps large and small and everywhere in between, primarily service applications using C# with periodic heavy doses of web development thrown in with ASP.NET MVC.

I frequently reach for CoffeeScript because I'm often hacking on projects that I already use it. While I generally think that transpiled-to-JS languages are an unnecessary fad that don't add substantive value, I think they also have their place in some situations.

Git is my go-to version control system. It's fast, efficient, and effective. Sometimes it's a little overwhelming for beginners, especially if they're coming from a VCS that's not distributed, but despite these minor drawbacks Git is a major part of my daily workflow.

John was very knowledgable and helpful. He's a good communicator and easy to work with. He had to cancel a session once but communicated it as soon as he could and rescheduled as soon as he was able. I had a good experience and was happy with how it was handled. I would seek his help in the future.

John is very knowledgable about Bluetooth, and was able to help us figure out some dead ends before we invested time implementing the wrong stuff.

John was awesome. He gave me good insight on how to build object in a thread-safe for Sidekiq. Before the mentoring session, he also made a point to get a general understanding where I was having trouble so we didn't waste time coming up to speed.
