I made ruby 10x faster. Let me show you how.
Urabe, Shyouhei, @shyouhei
Money Forward, Inc. hire Shyouhei, a long-time ruby-core committer, to contribute to the whole ruby ecosystem. Being a full-time ruby-core developer, his current interest is to speed up ruby execution by modifying its internals. Doing so is not straight-forward because of ruby's highly dynamic nature. To tackle this problem he is implementing a deoptimization engine onto ruby, which enables lots of optimization techniques that are yet to be applied to it.
