Software Development is my passion. Great knowledge about technologies, methods and paradigms are the foundation of my services that result in great software solutions.


Scrum, Kanban, Scrumban, extreme Programming (XP) are great, but they only create an advantage in combination with a clear product vision, short feedback cycles and space for innovations.


Quality in Software Development is more than just writing unit- and integration tests. A good understanding of customers needs, a solid runtime enviroment and security aspects are also in the focus of my daily work.


Teamwork, immediate Feedback and direct contact to users and stakeholders are some of the keyfacs for great and innovative software solutions.
