I have been an Apache Tomcat committer since November 2003. I initially worked on Tomcat in my free time but since August 2008 I have been employed by SpringSource (now part of Pivotal) to work on Apache Tomcat. I spend most of my time working on Tomcat but I also work on tc Server, Pivotal's Servlet & JSP container based on Apache Tomcat. Additionally, I lead the Pivotal security team.
I am the release manager Apache Tomcat 8 and 9 where I try to release a new version every month or so. I am currently focused on Tomcat 9 development which will support Servlet 4.0. I am a member of the JCP expert group for JSR 369.
Elsewhere at the ASF, I am a member of the ASF security and infrastructure teams and I am also on the Commons PMC where I focus on Commons Pool and DBCP.
