Skills

I'm an experienced software developer with 20 years experience, mainly in the world of Java.
Developed many frontend and backend applications.

On the frontend side developed using different technologies:
- Java-Applets
- Web Applications
  - Servlets/JSP
  - GWT/GXT
  - Javascript
  - Vaadin
  - VUE.js
- Eclipse RCP applications
- Java FX applications

On the backend side used technologies like:  
SQL, ORM, Hibernate, JPA, JEE (EJB, JMS) WebServices, Spring, div. application servers (Tomcat, JBoss), etc.

I am experienced in continous integration and deployment, using tools like
Apache Maven, Jenkins, Testing-Frameworks (JUnit, Selenium), Docker.

In the last years developed mobile applications based on own ideas and brought the apps to the stores (AppStore, Google Play).

I am happy if I can be a member of an Agile Team, but I am also able to work alone.
In the last 15 years I worked together remotely with an austrian customer, so I think borders between me and the customer are not a problem.
