As founder of lennlay, I have been trying to automate everything in IT for over 20 years. From software development and test automation to IT operations, I have gained instructive experience in large and small companies. Tools and technologies are constantly changing, but not my urge to learn new things and use them for IT automation.
As a specialist in IT automation, I develop an automated solution tailored to your needs. Call me at any time! Or contact me using the contact form.
I look forward to seeing you.

Implementation of a framework for test automation
In order to be able to carry out integration tests for a Java EE application (for mapping a hospital information system (HIS)), a test framework based on Selenium was created. With this it is possible to easily test the application in different environments, such as: OS (Windows, Linux), browser (Firefox, IE), databases (Oracle, Postgresql, Mysql, Sybase)
Design and implementation of a suitable infrastructure for developing and testing a JEE application. The process was: 1. Development of the code in Eclipse 2. Version control via Subversion 3. Buildtool: Maven. Checked-in changes were built promptly in the Continuous Integration Server (Hudson). This also triggered the integration tests and the deployment process of the application to the test installations.
In a small, distributed team (2 developers in Trier, 2 developers in Ghent, 3 developers in Vienna), a Java EE framework for mapping clinical paths was designed and implemented
