About Me

I have been performance tuning Java applications for more than 20 years. I got started working alongside Jack Shirazi. Together we authored the first full workshop on Java Performance Tuning. I also helped Jack launch javaperformancetuning.com. Since then I have written many articles and spoken at many conferences and user groups about performance tuning Java applications.

In 2006 I was named a Java Champion for my voice in the performance tuning space. I have been a JavaOne Rockstar multiple times. In 2008 I created the first iteration of a Java performance tuning methodology (jPDM). In 2012, I helped found JClarity where we built a diagnostic tool that was based on the jPDM methodology.

In 2019, Microsoft acquired JClarity. I worked there as a Principal Engineer in the Java Engineering Group, then briefly at Azul, before returning to independent consulting.
