Headius Enterprises

About Headius Enterprises

Headius Enterprises was launched in July 2024 to provide continuing support to the JRuby project and its users. We live and breathe open source and have decades of experience with Java, the JVM, Ruby, and of course JRuby itself. No other company in the world can match our level of expertise and professionalism when it comes to ensuring JRuby applications are stable and high-performance.

Charles Oliver Nutter, Architect and Technologist

Charles Oliver Nutter has been developing software professionally for over thirty years, building applications and libraries for the JVM since Java 1.0. During that time, Charles has released successful commercial software, managed multiple open-source projects, led development of government-scale enterprise applications, and contributed hundreds of thousands of lines of code to the world.

Charles is also a regular on conference circuits, delivering popular, deeply technical talks about Java, Ruby, the JVM, and everything in between. His presentations on JVM bytecode, invokedynamic, and the JVM JIT are among the most popular ever presented at JavaOne and other conferences.

As co-lead of the JRuby project, Charles has shown a steady hand, earning the project numerous awards and accolades. Charles himself has been named a Java Champion, a Ruby Hero, and a JavaOne Rock Star. In 2012, Charles won the JAX Innovators Award, and in 2018 he was awarded the Oracle Groundbreaker title alongside industry luminaries such as Guido van Rossum, creator of the Python language.
