Summary
30 years of project experience in IT, training, and internet projects of many different kinds have given me a broad base of experience. My clear personal focus is on turning business process analyses into project requirements and, after successful delivery, into operating concepts. In this role, I often act as a systems architect and build the bridge between business requirements and application development, all the way to solving implementation issues. My technical strengths are very good knowledge in IT architecture, software development, and interface technologies, as well as in the back end and front end of ERP, CMS, and e-commerce systems and the related technologies. Alongside many years of practical experience in managing editorial, IT, and development departments, I also have experience in project management.
