I have been developing with Java since around 2005, often in combination with Apache Maven. Efficient development also includes corresponding frameworks such as JUnit, JUnit Jupiter, Mockito, AssertJ, Testcontainers, etc. The analysis of unit, integration, and end-to-end tests is carried out using code coverage tools (e.g., JaCoCo) and mutation testing (PITest). Static code analysis (such as SonarQube) is an integral part of development, as is code review/pair programming. It should also be mentioned that appropriate security analyses are essential, as "recent" examples show.

Such development also requires a suitable environment (CI/CD). I have been able to set up, administer, and improve such environments using tools like Nexus, Docker, Jenkins, Drone, Gitea, GitHub, Shell, Go, Ansible, etc. Within the scope of such tasks, extensive knowledge of the Linux command line is very helpful.

Due to my many years of experience in the field of Apache Maven and also as an Apache Maven Committer / Apache Maven PMC, I possess expert knowledge in Apache Maven.

Furthermore, I have given talks at various conferences (BaselOne, JAX FOSDEM, CyberJug, JUG Darmstadt, JCON Europe, etc.). Additionally, I have extensive experience in training (Git, Maven, Subversion, Jenkins, etc.).

Various publications in magazines (e.g., Java Magazin, etc.).
