Charles works on JVM languages at Red Hat, focusing on Ruby but expanding to other languages soon. He has worked on JRuby for the past eight years and has been a JVM enthusiast since Java 1.0. Charles hopes to make JRuby the best Ruby implementation for high performance, big data, and heavy loads, and to use lessons learned from JRuby to help the JVM and other languages that run on it meet their potential.
