I don't think you explained it well from the boss's perspective. Why didn't he want you to rewrite the app from C++ to Ruby? Maybe it's not just that you did

I don't think you explained it well from the boss's perspective. Why didn't he want you to rewrite the app from C++ to Ruby? Maybe it's not just that you did too much work, but that you're making things tougher for everyone else. Do you have other ruby developers on staff? Does the support staff know how to support a ruby app? Maybe he wants you to take a weekend off so that you can be fresh on Monday.
