Mathematician in a former life, I am a Java software engineer working mostly on Open Source software.

Among my current projects you'll find:

  • Apache Log4j: a very popular logging library. In 2024 I had the chance to work full time on it and currently I am the chair of the Project Management Committee.
  • Extensions for Log4j and Tomcat: a personal project that enhances Apache Tomcat with Log4j.
  • Apache Commons a set of common Java libraries.
  • Some CycloneDX-related projects like sbom-enforcer.

Your sponsorship will be used to improve the project of your choice.
