I am an independent IT consultant and systems architect.

Clarity, focus and quiescence are the principles of my work. I am convinced that a balanced mind isthe best foundation to develop efficient solutions.

In more than 15 years of professional experience I have gained extensive knowledge and experiencewith large production systems, based on transactional and Java Enterprise technologies. My focusis on resilience, scalability and IT security.

I have accompanied projects in all phases, especially during the architecture, integration and testing,production and maintenance. Clear and concise documentation is an important part of my work.

I worked more than 7 years for BEA Systems as a consultant and have supported various BEAproducts for large customers in industry and business. Especially with the product Weblogic ServerI've worked over 13 years. After the BEA acquisition I could continue my successful workingrelationship with Oracle. The customers for whom I have worked include the Otto Group, theGerman Post AG, Siemens AG, VTG, Vattenfall, HSH Nordbank, Credit Suisse, Bertelsmann, Gruner+ Jahr, BHW Hameln, and FinanzIT Hannover.

I offer consulting for Java Enterprise projects.
